Cesar Sayoc, 56, was arrested Friday in South Florida. He has a lengthy criminal history.
At least 14 explosive devices were found and authorities are still searching for more.
The bombs were addressed to prominent Democrats and vocal opponents of President Trump.
None of the homemade devices exploded; FBI Director Chris Wray said they are not "hoax devices."
Sayoc faces 5 federal charges and is expected to appear in court Monday.
Following a nationwide manhunt, federal authorities have arrested a 56-year-old Florida man accused of sending a series of explosive devices to prominent Democrats and critics of President Trump. The suspect, Cesar Sayoc, was arrested Friday and charged with five federal crimes. He faces up to 48 years in prison.
Sayoc is accused of sending at least 14 homemade bombs to politicians including former President Barack Obama and former Secretary of State Hillary Clinton, among others. According to a criminal complaint, investigators said packages sent to his intended targets included their photos with red X's through them.
A fingerprint and a cell phone signal led investigators to Sayoc, who has openly and aggressively threatened Democrats online. Sayoc has an extensive rap sheet and has been an outspoken supporter of Mr. Trump.
Mr. Trump praised the quick arrest, saying, "These terrorizing acts are despicable and have no place in our country." He also denied his political rhetoric may have inspired Sayoc.

Retired cop who arrested suspect in 2002 says he's "not well"
The Miami police investigator who arrested Cesar Sayoc for threatening to blow up an FPL building in 2002 told CBS Miami he was not surprised when he heard Sayoc was arrested in connection with the recent spate of package bombs.
"Unfortunately, in law enforcement things like this can come back up," said the retired investigator, who spoke on condition his name not be released.
"I think anybody who wants to kill somebody, there are some issues there," he added. "I obviously think this person is not well."
According to a 2002 police report, Sayoc "threatened to blow up FPL and that `It would be worse than September 11.'" He also threatened to kill the FPL representative "if they cut his electricity."
"There was nothing significant that stands out about that case," the former bomb squad investigator explained.
"We were getting a lot of calls right after 9/11," he said, adding the complaint also came in the midst of the anthrax mail threats that were terrorizing elected officials. "Normally the bomb squad gets a couple of calls a month. Back then [in 2002] we were getting fifteen a day."
The investigator, along with an agent from the Florida Department of Law Enforcement, drove to Sayoc's apartment in Hallandale Beach to make the arrest. The police report listed Sayoc's occupation in 2002 as "Dry Cleaner."
The investigator said the arrest went smoothly and that Sayoc was cooperative. He eventually pleaded guilty to the bomb threat charge and was sentenced to one-year probation.
Now a private security consultant, the former bomb technician said soon after Sayoc was arrested Friday morning he started getting phone calls from former law enforcement colleagues. "I remembered the name, but not the picture," he said.
The former Miami police investigator said it was impressive, but not shocking, that federal agents made an arrest in the package bomb case so quickly. "The investigative tools available for law enforcement now are amazing," he said. "There are always leads available."
"Political violence must never, ever be allowed in America and I will do everything in my power to stop it," Mr. Trump said, calling for an "end to the politics of personal destruction." He added that "the media has a major role to play, whether they want to or not." The crowd then chanted "CNN sucks," while Mr. Trump looked on.
"The media has tried to attack the incredible supporters of our movement," he said, segueing to discussing his administration's accomplishments. "We want honest coverage from the media. That's all we want." He also repeated his claim that he was a "nationalist," not a "globalist," but he wants "to help the globe."
Mr. Trump began the rally by addressing Sayoc's arrest, applauding the FBI, the Secret Service, and state and local law enforcement. "We love our police, and we love our law enforcement," he said.
Grainy surveillance footage captured the moment federal agents set off a loud blast to take down Cesar Sayoc in Plantation, Florida, early Friday morning. A cellphone signal led agents outside to an AutoZone, where dozens of law enforcement agents surrounded him near his white van.
Tom Fiore, who works across the street, saw the arrest go down. "He had the look: 'OK, I'm done. I surrender y'all got me,'" said Fiore.
Suspect expected to appear in court Monday

The package was similar to bombs discovered this week. In a statement, Steyer, who has called for the impeachment of President Trump, said that the country faced more threats "than just one isolated terrorist in Florida.

Key fingerprint found late this week, FBI director says

Wray wouldn't say whether anyone else was involved with the bombs, saying the investigation was active and ongoing. "We do believe we've caught the right guy," the director said.
