FBI Director James Comey says the FBI and Justice Department have no information to substantiate President Donald Trump's claims that former President Barack Obama wiretapped him before the election.
Comey says no individual can order surveillance of an American. He says courts grant this permission after a rigorous application process.
Comey was testifying before the House intelligence committee. Comey said the Justice Department also asked him to share with the committee that the answer also applies to the Justice Department and its various components. The Justice Department oversees the FBI and other law enforcement agencies.
FBI Director James Comey and Mike Rogers, the director of the National Security Agency, say they have no evidence or intelligence that Russian cyber actors changed vote tallies in key states during last year's presidential election.
Testifying at a highly politically charged congressional hearing in the House, both said they had no evidence that any vote tallies were changed in Michigan, Pennsylvania, Wisconsin, Florida, North Carolina or Ohio.
The House intelligence committee is holding a hearing on Russian interference in the 2016 presidential election.
National Security Agency Director Michael Rogers says the intelligence community stands behind its January assessment that it is highly confident Russia interfered in the 2016 election with the goal of electing Donald Trump.
In a Monday morning tweet, Trump blamed Democrats for the investigation into his contacts and said the House intelligence committee should be focus on investigating leaks.
Rogers said that his agency is working to provide Congress the material it needs to investigate the intelligence agencies' findings.
Rogers was testifying before the House intelligence committee alongside FBI Director James Comey.
FBI Director James Comey is publicly confirming for the first time that the FBI is investigating Russia's efforts to interfere in the 2016 presidential election, including any potential coordination between Trump campaign associates and Russia's government.
Comey is testifying before Congress. He says he's authorized by the Justice Department to make the disclosure. Typically, the FBI does not discuss or even confirm the existence of ongoing investigations.
Comey says the probe is part of the FBI's counter-intelligence mission. He says the investigation includes the nature of any links between individuals associated with Trump's campaign and the Russian government, and whether there was any coordination between Russia's efforts and the campaign.
Comey says the investigation will also look at whether crimes were committed. He says he can't provide details about the investigation.
U.S. Rep. Frank LoBiondo will attend and question witnesses in the open House Permanent Select Committee on Intelligence hearing Monday morning, examining Russian activity in the 2016 presidential election.
The hearing features FBI Director James Comey, who will testify with Michael Rogers, the director of the National Security Agency.
The committee, with LoBiondo, also chairman of the House CIA Subcommittee, is investigating Russian hacking that intelligence officials said could have influenced the election.
The committee is also looking into any connection between Russia and President Donald Trump's associates.
The hearing will be held at 10 a.m. Monday.
