Federal investigators are continuing to investigate the motive of the gunman who opened fire during former President Donald Trump's rally Saturday, grazing the former president's ear, killing one bystander and critically wounding two others.
In an address from the Oval Office on Sunday night, President Biden said the shooter's motivations were still unclear, and urged Americans to reject politically motivated violence.
"There is no place in America for this kind of violence, for any violence, ever. Period. No exceptions. We can't allow this violence to become normalized," Mr. Biden said. "The political rhetoric in this country has gotten very heated. It's time to cool it down. We all have a responsibility to do that."
More details emerged Sunday about the shooter, identified as 20-year-old Thomas Matthew Crooks, of Bethel Park, Pennsylvania, who was killed after he opened fire. Rudimentary bomb-making material was found at the gunman's home and in his vehicle. He was a member of a local gun club, and a former classmate said that he had tried out for the high school rifle team but didn't make it.
The FBI is investigating whether the shooter was a politically motivated homegrown domestic violent extremist, and investigators are still combing through his background. Justice Department officials told reporters that investigators have the shooter's phone and were examining it at the FBI lab in Quantico, Virginia.
Law enforcement sources said bystanders spotted the shooter with a rifle on a roof about 400 feet from where Trump was speaking in Butler, Pennsylvania, and reported his presence to authorities. The sheriff of Butler County said a local police officer was hoisted by another officer to look onto the roof. The shooter pointed his rifle toward the officer, who let go and fell off.
The shooter then turned toward the rally and fired six to eight rounds using an AR-style weapon. A Secret Service sniper soon shot and killed him. Trump was quickly whisked from the stage by armed agents, blood running down the side of his face.
Trump posted on his social media platform Truth Social on Sunday morning, saying it "was God alone who prevented the unthinkable from happening."
Mr. Biden has ordered an independent review of the security at the rally to assess what took place, and said he directed the Secret Service to examine security measures for this week's Republican National Convention in Milwaukee, where Trump was formally named as the party's nominee Monday. Trump landed in the city Sunday evening.
Trump and Mr. Biden spoke Saturday night in what a White House official characterized as a "good, short and respectful" call.
Sniper who took out gunman fired one round
The Secret Service sniper who neutralized the gunman fired one round and was assisted by a spotter, according to two federal law enforcement officials with knowledge of the response to the shooting.
The sniper who took out the gunman was located on the roof behind and to Trump's to his left — the square farthest to the right in the below map.
FBI continues looking into Trump shooter's background
The man who attempted to assassinate former President Donald Trump purchased 50 rounds of ammunition from a gun store in Bethel Park, Pennsylvania, before arriving at the rally site, according to a law enforcement bulletin from the Department of Homeland Security and the FBI obtained by CBS News.
The FBI is investigating whether the shooter "was motivated by a violent extremist ideology or had any association with additional plotters or co-conspirators."
Investigators found three suspected improvised explosive devices after the shooting, including two in the shooter's vehicle parked near the rally site, the bulletin reads.
Both agencies advised law enforcement about the potential for retaliatory acts of violence following Saturday's shooting given the online threats of violence after the attempt on Trump's life.
"Some individuals' reactions to politically and socially divisive topics have prompted violence ... and some individuals — including some (Domestic Violent Extremists) — potentially will view political and social tensions as an opportunity to use or promote violence to further their ideological goals," the bulletin reads.
Three snipers were stationed inside building used in Trump assassination attempt
There were three snipers stationed inside the building the shooter used during Saturday's shooting of former President Donald Trump, a local law enforcement officer with direct knowledge of the incident tells CBS News.
The operations plan had them stationed inside the building looking out windows toward the Trump rally. The information about the three snipers being inside the building was first reported by BeaverCountian.com.
One of the snipers inside saw Thomas Matthew Crooks outside and looking up at the roof, observing the building and disappearing, a local law enforcement officer tells CBS News.
Crooks came back, sat down and looked at his phone. At that point, one of the snipers took a picture of him. Crooks took out a rangefinder and the sniper radioed to the command post. Crooks disappeared again and then came back a third time with a backpack. The snipers called in with information that he had a backpack and said he was walking towards the back of the building.
Officers believe that Crooks might have used an air conditioning unit to get on top of the roof.
By the time other officers came for backup, he had climbed on top of the building and was positioned above and behind the snipers inside the building, the officer said.
Two other officers who heard the sniper's call tried to get onto the roof. State police started rushing to the scene, but by that time, a Secret Service sniper had already killed Crooks, the officer said.

Former Secret Service agent reacts to security breach during assassination attempt
As former President Donald Trump continues to recover from the injury sustained during Saturday's attempt on his life, the questions of culpability remain.
Ron Layton, a former Secret Service agent, tells CBS Pittsburgh that he and others in law enforcement are "furious" with the lack of protection that led to the shooting.
"People who worked in the Secret Service and people in the active service are furious," Layton said. "We are angry. I am angry."
A 20-year-old gunman on a rooftop approximately 400 feet away fired on and injured Trump, killing one bystander and critically wounding two others.
"He shouldn't have access to the roof," Layton said. "That's the job, that's why you staff that building. So, that should have never happened."
Michael Slupe, the sheriff of Butler County, told CBS Pittsburgh that there was a pre-planning meeting with local law enforcement and the Secret Service, but that he couldn't remember if the building the shooter used was brought up.
"I don't remember that as part of the conversation," Slupe said. "It wasn't part of our pre-plan. And obviously, I can't comment because that would be levels higher than the sheriff to answer that question."

Trump says assassination attempt had "impact"
The attempted assassination on former President Donald Trump had "an impact," he told ABC News on Monday.
Trump was asked by ABC News' Jonathan Karl if the attempt on his life had changed him.
"I don't like to think about that, but, yes, I think has an impact," he said, adding that he hoped the bandage on his ear would be removed by the time he speaks on Thursday to the Republican National Convention.
Hospital staff where Trump was treated praised for response effort
Three hours passed from when the staff at Butler Memorial Hospital were notified that former President Donald Trump had been injured during an assassination attempt and the Secret Service cleared out following his treatment. Hospital officials told CBS Pittsburgh their contingency plans worked as they should.
"It's in the back of everybody's mind who this person is. But they do what they do best, and that's to focus on the patient right in front of them," said Dave Rottinghaus, a Butler Memorial Hospital emergency doctor.

Sheriff says building used by shooter "wasn't our responsibility"
A Pennsylvania sheriff said his agency wasn't responsible for protecting or securing the building that the shooter used to attack Saturday's rally.
CBS Pittsburgh station KDKA-TV reporter Andy Sheehan asked Butler County Sheriff Michael Slupe if there was enough communication from the Secret Service about securing the building.
"I can't speak to that because, you know, as far as the building goes, I don't know because it wasn't our responsibility, but they did have a very good briefing," Slupe told KDKA-TV. "And, like I said earlier, somewhere along the line, you have a briefing and you identify, adapt and overcome. And there are a lot of well-trained police officers that totally have the ability to do that."
Asked if there was a plan to secure the building, Slupe said, "I have no idea about that. I have no idea. I don't."
Slupe also said his agency wasn't asked to sweep the building.
"No, the sheriff's office was not asked to do that, and I don't know whose responsibility that would have been if that was in their plan," he said.
Shooter's father called police after assassination attempt
The shooter's father called local police after the shooting took place, according to three law enforcement officials. CBS News does not have details about the nature of the call or the exact timing of the call. The family is cooperating with federal investigators, according to the FBI.

Shooter's weapon was bought well before attack, source says
The gun used in the attack against former President Donald Trump was not newly purchased, according to a source familiar with the matter. The weapon was legally purchased by the shooter's father well before Saturday's attack.

Secret Service director to appear before House Oversight panel next week
Secret Service Director Kimberly Cheatle is slated to testify before the House Oversight and Accountability Committee next Monday about the assassination attempt on former President Donald Trump, the committee announced.
Lawmakers will gather information from Cheatle about the shooting at Trump's rally, which shocked the nation and raised questions as to how the shooter was able to gain access to a rooftop so close to where the former president was addressing the crowd of supporters.
"The United States Secret Service has a no-fail mission, yet it failed on Saturday when a madman attempted to assassinate President Trump, killed an innocent victim, and harmed others," committee Chairman James Comer said in a statement. "We are grateful to the brave Secret Service agents who acted quickly to protect President Trump after shots were fired and the American patriots who sought to help victims, but questions remain about how a rooftop within proximity to President Trump was left unsecure."
Comer, a Kentucky Republican, indicated that Cheatle will face questions about security lapses at the rally and how to prevent another attack from happening again.
Investigators return to shooter's home
Investigators returned Monday to the shooter's home in Bethel Park, about a 25-minute drive south of Pittsburgh.
At around 10 a.m., a few SUVs rolled up to the street that the shooter lived on. About four men got out of the SUVs. One was wearing a patch that said Pittsburgh Federal Bureau of Investigation, with SWAT also in the middle of the embroidered patch.
They split up in pairs and were knocking on doors, in a lot of cases to no avail. One pair was let into the shooter's home and left after a few minutes.
BlackRock says shooter appeared in company ad

The ad, which was produced in 2022, was filmed at Bethel Park High School, where the shooter was a student at the time. BlackRock filmed the spot, part of a series for teachers managing their retirement assets, in a classroom led by a real teacher and which featured real students. The shooter was one of those students, BlackRock told CBS MoneyWatch.

Trump Media stock price surges after failed assassination attempt
Trump Media & Technology Group's stock price soared 32% Monday.
The company, which owns the Truth Social platform, jumped $9.98 to $40.87 in morning trading. The jump reverses a six-week slump in Trump Media shares, which have exhibited volatile trading patterns since going public in March.
Trump Media — whose ticker symbol, "DJT," is the same as the former president's initials — is viewed by some as a so-called meme stock because its wild swings are influenced largely by social media enthusiasm rather than the business fundamentals that investors typically look for, such as profit and revenue growth.
Secret Service director says agency will "participate fully" in independent review
Secret Service Director Kimberly Cheatle pledged in a statement Monday that the agency will "participate fully" in the independent review of security at former President Donald Trump's rally that President Biden announced Sunday. Cheatle also said the agency will work with the appropriate congressional committees conducting oversight of the security plans before the rally.
"The Secret Service is tasked with the tremendous responsibility of protecting the current and former leaders of our democracy," she said. "It is a responsibility that I take incredibly seriously, and I am committed to fulfilling that mission."
Cheatle said the Secret Service has made changes to Trump's security detail following the assassination attempt to ensure his continued protection for this week's Republican National Convention in Milwaukee and the rest of the presidential campaign.
The Secret Service provided Trump's detail with additional security enhancements in June, she said.
Cheatle, who took the helm of the Secret Service in September 2022, said the agency is working with federal, state and local agencies to learn more about what happened at the rally, how it occurred and how it can be prevented from happening again.
With the Republican convention kicking off, the Secret Service chief said she is "confident" in the security plan put in place for the week, which Cheatle said was reviewed and strengthened following the shooting.
Cheatle also praised the Secret Service agents who were on the ground at the rally in Butler County, Pennsylvania, and offered condolences to the family and friends of Corey Comperatore, who was killed at the rally.
"Secret Service personnel on the ground moved quickly during the incident, with our counter sniper team neutralizing the shooter and our agencies implementing protective measures to ensure the safety of former President Donald Trump," she said.

King Charles writes letter to Trump after assassination attempt
King Charles III wrote a private letter to former President Donald Trump after he was injured in an assassination attempt at a Pennsylvania rally over the weekend, Buckingham Palace confirmed on Monday.
In a statement, the king's press secretary said the private letter was delivered via the United Kingdom's embassy in Washington.
"We do not divulge contents of such private correspondence, but safe to surmise that the sentiments are in keeping with those communicated by the [prime minister]," the statement said.
New British Prime Minister Keir Starmer wrote on social media that he was "appalled by the shocking scenes at President Trump's rally and we send him and his family our best wishes. Political violence in any form has no place in our societies and my thoughts are with all the victims of this attack."
Starmer also had a call with Trump on Sunday.
Residents allowed to return to homes in Trump shooter's neighborhood
Bethel Park residents are being notified that they're allowed to re-enter their homes, according to local law enforcement on the scene, after residents were forced to evacuate the area as agencies swarmed the home connected to the gunman who tried to assassinate former President Donald Trump.
The FBI has, at least for now, left the scene on Milford Drive. CBS News congressional correspondent Scott MacFarlane posted on X, formerly known as Twitter, that the FBI "has searched the shooter's home and vehicle to collect additional evidence."
Lights remained on, and two SUVs were parked at the one-story home where the shooter, Thomas Crooks, and his parents lived, according to CBS News Pittsburgh's Ricky Sayer:

Trump on attempt on his life: "I'm supposed to be dead"
Former President Donald Trump told the New York Post on Sunday he was "supposed to be dead" after an assassination attempt he described as "surreal."
"I'm not supposed to be here, I'm supposed to be dead," Trump told the Post in an interview aboard his plane en route to Milwaukee for the Republican National Convention, where he is set to be confirmed as the party's presidential candidate.
Trump told the newspaper he would have been killed if he hadn't tilted his head slightly to the right to read a chart on illegal immigrants while addressing the rally. "By luck or by God, many people are saying it's by God I'm still here," he said.
He praised the Secret Service agents for killing the shooter. "They took him out with one shot right between the eyes," he said.
Trump said the attempt on his life made him decide to rewrite the speech he'd prepared for the convention.
He said the original one was "extremely tough," about President Biden's "horrible administration. But I threw it away" for one said he hopes will "unite our country."
"But I don't know if that's possible," he added. "People are very divided."

Timeline of attempted assassination of former President Trump
Thousands of people arrived at Pennsylvania's Butler Farm Show, a roughly 100-acre fairground used for agricultural exhibitions, on Saturday to see former President Donald Trump speak at a campaign rally.
Butler County voted overwhelmingly for Trump in 2020, so the crowd was expected to be friendly, but things took a sudden, deadly turn a little after 6 p.m. local time, minutes after the former president and presumptive Republican nominee began speaking.

Biden campaign responds to GOP officials blaming president's rhetoric for assassination attempt
The Biden campaign on Sunday night responded to Republican officials who have said or implied President Biden's rhetoric was responsible for the attempted assassination of former President Trump.
"In a moment when Americans should come together and unite to condemn this horrifying attack, anyone — especially elected officials with national platforms — politicizing this tragedy, spreading disinformation, and seeking to further divide Americans isn't just unacceptable — it's an abdication of leadership," a campaign official told CBS News.
The Biden campaign halted its ads and other communications in the wake of the shooting Saturday night.
Mr. Biden is expected to use an upcoming interview with NBC's Lester Holt to reiterate the need to end political violence and condemn the attack on Trump.
The campaign is expected to pick back up following that interview, although it's not clear when Mr. Biden's campaign would resume TV ads. Sources told CBS News the campaign understands it must be responsible in how it goes about criticizing Trump moving forward, but it is clear-eyed that there are less than four months before the election.
Butler County district attorney defends local law enforcement
Butler County District Attorney Richard Goldinger told CBS Pittsburgh that while local law enforcement provided assistance at former President Trump's rally on Saturday, "the security would have been under the purview of the Secret Service."
"We provided some snipers for them, some quick response teams, but we didn't have any responsibility with securing the perimeter or anything outside of that venue," Goldinger told CBS Pittsburgh's Jennifer Borrasso. "And the hierarchy of command for the security would have been the Secret Service, followed by the state police and then the local municipal departments."
FBI notes rise in threats of violence, conspiracy theories in aftermath of Trump rally shooting
In a call with state and local law enforcement partners earlier Sunday, the FBI noted a rise in conspiracy theories and calls for civil war online in the aftermath of the attempted assassination of former President Trump.

Biden says political rhetoric has become too heated: "It's time to cool it down"
President Biden addressed the nation from the Oval Office Sunday evening, calling for Americans to settle their differences at the ballot box, not by violence. He also called for unity in a time of great division.
"The political rhetoric in this country has gotten very heated," he said. "It's time to cool it down."
The president reiterated gratitude that Trump wasn't seriously injured, and expressed sorrow over the death of 50-year-old rally attendee Corey Comperatore.
"A former president was shot, an American citizen killed, while simply exercising his freedom to support the candidate of his choosing," the president said.
Mr. Biden urged Americans not to jump to conclusions as law enforcement continues to investigate. The 20-year-old shooter was shot and killed by a Secret Service sniper.
"We do not know the motive of the shooter yet," the president said. "We don't know his opinions or affiliations. … Law enforcement professionals as I speak are investigating those questions."
Mr. Biden said the attempted assassination was the latest in a series of violent political acts, mentioning the Jan. 6, 2021, assault on the Capitol and the foiled plot to kidnap Michigan Gov. Gretchen Whitmer.
"We can't allow this violence to be normalized," he said. "The power to change America should always be in the hands of the people, not in the hands of a would-be assassin."
The president encouraged Americans to recommit to unity, and place the country before politics.
"Nothing is more important for us right now than standing together," he said. "We can do this."

Trump describing assassination attempt to friends
Trump remains in good spirits and has described the assassination attempt to friends, according to two people familiar with the discussions who were not authorized to speak publicly.
He has detailed what it was like onstage to several family members, aides and friends, recounting how the bullet sounded and how he noticed blood on his hand after he touched his ear, these people said.
Trump has recalled his conversation with a doctor and medical professionals who treated him. He is reflecting to some about how close he came to a fatal injury.
He has told many people the convention must go on and is eager to appear before his supporters soon, the people said. He has not discussed his vice presidential selection with these sources, and people are mostly resisting bringing the matter up with him unless they're his top aides.

Another former classmate of Crooks said he was "nerdy and shy" but friendly
A high school classmate of Thomas Matthew Crooks told CBS News he never personally saw Crooks bullied in school.
Mark Sigafoos, 19, took two classes and graduated with Crooks from Pennsylvania's Bethel Park High School in 2022.
"Shocked is an understatement," Sigafoos said, upon learning that Crooks was the shooter at the Trump rally.
Sigafoos said that while Crooks was "definitely nerdy for sure," he "never gave off that he was creepy or like a school shooter."
"He seemed like he wouldn't hurt a fly," Sigafoos said.
The shooter was smart, approachable and friendly, Sigafoos said, adding that they sat next to each other in an AP Economics class, where Crooks was frequently engaged and volunteering answers.
"It really makes me wonder what happened in the two years after graduating and maybe what outside influences there were," Sigafoos said.
Armed officer encountered gunman on roof before shooting began, sheriff says
An armed municipal officer with Butler Township encountered the gunman before the shooting, Butler County Sheriff Michael Sloupe confirmed to CBS News.
The officer and others had been previously alerted to a suspicious person and began searching for him right away, Sloupe told CBS Pittsburgh reporter Jen Borrasso.
At some point, the officer was hoisted by another officer onto the roof of the building where the shooter was in position. The shooter focused his rifle towards the officer, who let go and fell off the roof. Then the shooter began firing into the crowd, according to Sloupe.
Source: Bomb-making material found in shooter's home, vehicle
A law enforcement source confirmed that authorities found rudimentary bomb-making material at the gunman's residence and in his vehicle. The FBI is analyzing the devices at Quantico.
Shooter had gun club membership
Crooks had a membership to a local gun club in Clairton, Pennsylvania.
"We can confirm that Mr. Crooks was a member of the Clairton Sportsmen's Club," Clairton Sportsmen's Club president Bill Sellitto said. "Beyond that, the club is unable to make any additional commentary in relation to this matter in light of pending law enforcement investigations. Obviously, the Club fully admonishes the senseless act of violence that occurred yesterday. The Club also offers its sincerest condolences to the Comperatore family and extends prayers to all of those injured, including the former president."
Secret Service says there are no changes to plans to secure Republican National Convention
The Secret Service said Sunday that it has made no changes its security plan for the Republican National Convention, and is "confident in the security plans," in the wake of the Trump rally shooting.
At a news conference about the convention security, the Secret Service said there have not been any discussions about banning guns in the soft perimeter, the area immediately outside the hard perimeter of the convention. The inner perimeter is the area that requires credentials for entry.
The Milwaukee police chief, Jeffrey Norman, said that under state law, guns are allowed in the soft perimeter because "it's a state law — we can't change that," adding that law enforcement had to respect 2nd Amendment rights.
He said he did not anticipate any changes to the security perimeter.
After last night's assassination attempt against Trump, the Republican National Convention has put federal, state and local law enforcement officials on even higher alert heading into the convention.
The convention, where the GOP will come together to officially nominate Trump, is expected to continue as planned in Milwaukee, Wisconsin, this week.

House speaker calls Secret Service director to testify about Trump rally shooting
Congress will conduct an investigation into the assassination attempt against Trump, House Speaker Mike Johnson said.
Johnson plans to call Secret Service, FBI and Homeland Security officials to appear before lawmakers. House Oversight Committee Chair James Comer posted a letter inviting Secret Service Director Kimberly A. Cheatle to testify at a hearing on July 22.
Questions are being raised about how shooter Thomas Matthew Crooks was able to get so close to Trump. He climbed onto the roof of a shed about 400 feet from the podium and opened fire before he was killed by a Secret Service sniper.
A.T. Smith, a former Secret Service deputy director and CBS News national security contributor, told "Face the Nation" that sources said the agency had an "adequate amount of time" to prepare for the rally.
"The most glaring question to be asked is: how did this individual make it to the roof of that building with a long rifle, an AR-15-type rifle, apparently?" Smith said.
Secret Service spokesman Anthony Guglielmi said in a statement that the agency had implemented protective measures for the rally. Personnel positioned around the stage where the former president was speaking rushed to surround Trump and sweep him off the stage to his motorcade after the shooting. In another statement Sunday, the Secret Service denied any suggestion that protective resources had been denied.
"The assertion that a member of the former President's security team requested additional security resources that the U.S. Secret Service or the Department of Homeland Security rebuffed is absolutely false," Guglielmi said. "In fact, recently the U.S. Secret Service added protective resources and capabilities to the former President's security detail."
GOP House campaign arm pauses digital fundraising efforts
The National Republican Congressional Committee, the GOP House campaign arm, has paused its digital fundraising efforts since the shooting, according to an NRCC spokesperson. It's not clear how long the freeze will remain in effect.

Biden "sincerely grateful" Trump's doing well, will address nation from Oval Office tonight
President Biden said in brief remarks at the White House that he was "sincerely grateful" that Trump is doing well, adding that he spoke with the former president on Saturday night. He characterized the call as a "short, good" conversation, and he also said he would address the nation from the Oval Office at 8 p.m. tonight.
Mr. Biden called for unity in the wake of the assassination attempt, and he denounced political violence.
"There's no place in America for this kind of violence, or any violence for that matter," the president said. "An assassination attempt is contrary to everything we stand for as a nation. It's not who we are as a nation."
The president said that unity is the "most elusive goal of all" and added that "nothing is more important than that right now. Unity."

Melania Trump, the wife of former President Donald Trump, issued a statement on Sunday, calling the attempted assassination of her husband a "heinous act."
"America, the fabric of our gentle nation is tattered, but our courage and common sense must ascend and bring us back together as one," the former first lady said in a statement shared on social media.
She said that when she watched the "violent bullet" strike her husband, she realized that her life and that of the couple's son Barron was "on the brink of devasting change."

The former first lady thanked everyone for their support, in particular the law enforcement officials who risked their lives to protect that of her husband.

Congressmen introducing bipartisan bill providing Trump, Biden and RFK Jr. with enhanced security
Democratic Rep. Ritchie Torres of New York and Republican Rep. Mike Lawler of New York are planning on introducing bipartisan legislation to provide Trump, Mr. Biden and Robert F. Kennedy Jr. with enhanced Secret Service protection, according to Torres's office.
"Last night's attempted assassination of former President Trump was a dark moment in our nation's history," the two congressmen said in a joint statement. "As reports continue to emerge, it's clear that more protection is needed for all major candidates for president. That's why we're planning on introducing bipartisan legislation providing President Joe Biden, former President Donald Trump, and presidential candidate Robert Kennedy, Jr., with enhanced Secret Service protection. Anything less would be a disservice to our democracy."
The RFK Jr. campaign has long been asking for Secret Service protection. His father, Robert F. Kennedy, was assassinated during the 1968 Democratic presidential primaries.

Harris cancels Tuesday campaign event in Florida in light of shooting
Vice President Kamala Harris was scheduled to campaign on reproductive rights Tuesday in Palm Beach County, Trump's backyard.
But a Biden-Harris campaign official said the event has been canceled following Sunday's shooting. In the aftermath, Harris said she was "relieved" Trump wasn't seriously injured.
"Violence such as this has no place in our nation," she said in a statement. "We must all condemn this abhorrent act and do our part to ensure that it does not lead to more violence."
Shooter spotted outside security perimeter as people were arriving at rally, sources say
Two law enforcement sources told CBS News that the shooter was spotted outside the security perimeter as people were filing into the rally, and he was reported by a bystander to the Butler County Sheriff's Office. He was identified as a suspicious person by police, the sources said.
The sources said officials momentarily lost track of the gunman. Six minutes after Trump started talking, the shooter crawled up the side of the shed, and "popped up" on the roof, then immediately began shooting, the law enforcement sources said. He was lying flat on the shed — not walking or standing. There was very little time that passed between when he popped up and when shots rang out.
The gunman fired 6 to 8 rounds using a semi-automatic AR-style rifle from his position approximately 400 feet from the podium.
Secret Service counter sniper teams "had him" within seconds — the threat was neutralized almost immediately after shots were fired, the law enforcement sources said.

Details emerge about the shooter
Details about the shooter, Thomas Crooks, began surfacing after the FBI identified him as the subject involved in the assassination attempt. He was a 2022 graduate of Bethel Park High School.
A law enforcement official told CBS News that the Secret Service and FBI are investigating the gunman's background and speaking with his family.
No foreign terrorism ties are known to Crooks at this time and the gunman was not on law enforcement's radar, a law enforcement official said.
There was no indication that Crooks had a connection to any military branch, officials confirmed to CBS News.
Crooks' political leanings were not immediately clear. Records show he was registered as a Republican voter in Pennsylvania but previously made a $15 donation to a Democratic-aligned group, CBS Pittsburgh station KDKA reported.
Secret Service says it is "untrue" that Trump team asked for more protection
The Secret Service issued a statement on Sunday morning saying it was "untrue" that a member of Trump's team had requested more Secret Service protection.
"There's an untrue assertion that a member of the former President's team requested additional security resources & that those were rebuffed. This is absolutely false. In fact, we added protective resources & technology & capabilities as part of the increased campaign travel" protocols, the Secret Service said in a statement.
Trump has had a Secret Service detail since 2016, and all former presidents and their spouses have Secret Service protection for the remainder of their lives, unless that person declines. Trump was given additional protection in June as part of the protocol for the process for a presumptive presidential nominee. Those additional protections include additional manpower, counter sniper, drones and robotic dogs.

"We also urge you to recognize the political polarization in this heated election," the managers said, instructing staff not to comment publicly on the incident. "We condemn all forms of violence, and will not tolerate dangerous rhetoric on social media."
Johnson: "Everyone needs to turn the rhetoric down"
House Speaker Mike Johnson said Sunday on NBC's Today that he spoke with Homeland Security Secretary Alejandro Mayorkas last night, and that "everyone needs to turn the rhetoric down."
"We can have heated political discourse and debates but it shouldn't be personal and we shouldn't be targeting people," Johnson said. "I mean, look, President Biden himself said in recent days, it's time to put the bullseye on Trump. I mean, I know that he didn't mean what is being implied there, but that kind of language on either side should be called out and we have to make clear that this is part of our system. We can have vigorous debate, but it needs to end there."
Johnson has called on the House to conduct an investigation into the shooting.
Law enforcement search home of Trump rally shooter
Law enforcement officials on Sunday swarmed the home believed to be connected with the shooter in the assassination attempt of former President Donald Trump.
Public records show the home is that of 20-year-old Thomas Crooks, who federal law enforcement officials identified as the shooter who opened fire at the rally in Butler on Saturday evening.
One neighbor, who lives only a few homes down the road from the gunman, told CBS Pittsburgh that police evacuated her home in the middle of the night. She was told noon on Sunday was the earliest she could be allowed back into her home.
"They asked us to leave our house. They told us it was a state of emergency, no warning, just a knock on the door in the middle of the night," Kelly Little said. "They told us we could come back in a couple of hours, likely."
