Here's what we know from the House hearing with FBI Director James Comey

FBI Director James Comey and National Security Agency Director Mike Rogers appeared Monday before the House Intelligence Committee. Here's what we know from their testimonies so far.

The FBI and Justice Department do not believe Obama wiretapped Trump

"The FBI and the Justice Department have no information to support" President Trump's claims that the Obama administration had tapped Trump's offices during the campaign, Comey said.

This is consistent with what Comey has done in the past about the wiretapping claims. The day after the president first made the allegations, Comey asked the Justice Department to rebuke the claims.

Additionally, committee Chairman Devin Nunes, R-Calif., added: "Let me be clear, we know there was not a wiretap on Trump Tower. However, it's still possible that other surveillance activities were used against President Trump and his associates.'"

Comey's statement comes the week after the Senate Intelligence Committee said it had found "no indications that Trump Tower was the subject of surveillance."

The FBI is investigating whether Russia interfered with the 2016 election

The FBI for the first time publicly confirmed investigations into Russian interference with the 2016 presidential election. This included the revelation that Russian hackers used a third party to communicate with WikiLeaks.

"As you know, our practice is not to confirm ongoing investigations, especially those investigations that involve classified matters," Comey told the committee. "But, in unusual circumstances, where it is in the public interest, it may be appropriate to do so."

This, he said, was one of those circumstances.

Comey and Rogers both said they were not aware of any evidence that any votes in the election were changed because of interference from Russia.

That investigation includes looking into links between the Trump campaign and Russia

Officials will probe any links between people associated with the Trump campaign and the Russian government and whether there was any coordination between the campaign and Russian efforts, Comey said.

He noted that because the investigation is ongoing, he couldn't say anything else about what the investigation entailed or who they were investigating.

The U.S. did not seek help from the British to conduct surveillance

The NSA's Rogers called the president's claims that Obama had asked the British to surveil Trump "frustrating." The United Kingdom has protested claims by Trump allies that the British were involved with wiretapping.
