Here are some of the top disclosures from Comey's appearance before the Senate Intelligence Committee.
THE RUSSIA INVESTIGATION
Comey said Trump fired him on May 9 to try to undercut the Federal Bureau of Investigation's probe. While the firing almost immediately prompted allegations that this was the case, this was the first time Comey made the accusation in a public forum.
Comey said the Trump administration had lied and defamed him and the FBI after his firing by saying the agency was in disarray and that the workforce had lost confidence in him.
Comey also said he started writing memos about his meetings with Trump after an encounter with the president-elect on Jan. 6 because he was concerned Trump might lie about it. Comey said he never felt the need for such a record from meetings with Trump's two predecessors, Barack Obama and George W. Bush.
THE FLYNN INVESTIGATION
Comey confirmed that when Michael Flynn was fired as national security adviser on Feb. 13, the retired lieutenant general was under criminal investigation for statements in connection with Russian contacts and for the contacts themselves.
ATTORNEY GENERAL SESSIONS
Comey said he shared memos of his nine conversations with Trump with investigators for Robert Mueller, the special counsel investigating possible ties between the Trump campaign and Russia.
The former FBI director said he also showed copies of a memo memorializing talks with Trump to people outside the Justice Department. He said he asked a close friend, a Columbia Law School professor, to share the memo's content with a reporter. Comey said he was prompted to make that request by a tweet from Trump following his firing.
The professor, Daniel Richman, confirmed to Reuters on Thursday that Comey was referring to him.
CLINTON EMAIL INVESTIGATION
Comey said Obama's attorney general, Loretta Lynch, directed him to refer to the probe of Hillary Clinton's emails as a "matter" rather than an "investigation." That and her private tarmac meeting with former president Bill Clinton before the FBI's decision on whether Hillary Clinton may have criminally mishandled government information led Comey to disclose the agency's findings ahead of schedule last summer.
