The FBI is investigating reported cyber intrusions at Clinton campaign
The FBI is investigating reported cyber intrusions at both Hillary Clinton's campaign and the Democratic Congressional Campaign Committee, which is tasked with raising money for House races, CBS News confirmed, sources told senior investigative producer Pat Milton. Reuters was the first to report the Clinton campaign breach.
Sources told Milton it's not yet known who is responsible or whether the attack is related to the larger breach of the Democratic National Committee that was made public earlier this week, when Wikileaks released the organization's private emails.
However, Clinton campaign spokesman Nick Merrill said the intrusion of the campaign concerned a DNC analytics data program used by the campaign and a number of other organizations.
Merrill said a review conducted by outside cyber security experts has found "no evidence" that the campaign's "internal systems have been compromised." The campaign refused to give additional details about the program or nature of the attack.
The DNC breach resulted in the release of more than 19,000 DNC emails just before the beginning of the party's nominating convention this week, some of which showed bias among top Democratic officials against Bernie Sanders during the primary campaign. As a result, Rep. Debbie Wasserman Schultz, D-Florida, announced last weekend that she would resign her position as DNC chair by the end of the week.
The DNC attack is believed to be linked to affiliates of the Russian government, CBS News has reported.
Clinton campaign officials have suggested that Russia breached the network at the DNC in order to influence the U.S. presidential election in favor of Donald Trump. While President Obama declined to speculate on the motivations, he told NBC News on Wednesday that "anything's possible."
During a press conference Wednesday, Trump invited Russia to try and track down 30,000 emails that Clinton deleted from her time as secretary of state, although he later said his remark was meant to be sarcastic.
He also repeatedly claimed that he has "nothing to do with Russia" including having no financial relationship, though he's still refusing to release his tax returns to prove it. CBS News' Julianna Goldman reported Friday, however, that Trump's connections to Russia and to President Vladimir Putin go back years and he has been trying to bring his brand to Moscow for decades.
