President Donald Trump abruptly fired James Comey as director of the FBI in the midst of the law enforcement agency's investigation into whether Trump's presidential campaign was connected to Russian meddling in the election. In a letter to Comey, Trump said the dismissal was necessary to restore the public's trust and confidence.
Comey told a congressional committee that Trump tried to pressure him to drop an investigation into one of his senior advisers then "spread lies" about the affair, and why he fired Comey.
Often lauded for his independence, Comey had earlier come under intense scrutiny for his role in the agency's investigation into the email practices of Trump's opponent, Democrat Hillary Clinton, including a pair of letters he sent to Congress on the matter in the final days of last November's election.
Here is a look at key moments in Comey's tenure, the lead-up to Trump's decision to fire him and what followed.
Sept. 4, 2013: Comey is sworn in to office as the seventh director of the FBI. He was nominated for the post by President Barack Obama and confirmed by the Senate.
July 5, 2016: Holds news conference to announce that "no reasonable prosecutor" would bring criminal charges against Hillary Clinton, the Democratic presidential candidate, over her email practices as secretary of state, but criticizes Clinton and her staff for being "extremely careless" in their handling of classified material.
July 5, 2016: Republican presidential candidate Donald Trump calls the FBI's decision not to bring criminal charges against Clinton the greatest example yet that the system is "rigged."
U.S. & World
July 7, 2016: Comey vigorously defends the decision not to prosecute Clinton over her use of a private email server as secretary of state. Under an onslaught of Republican criticism, Comey says that to charge Clinton would have been unwarranted and mere "celebrity hunting."
Oct. 28, 2016: Days before the election, Comey informs Congress by letter that he was reopening the investigation into Clinton's email practices based on new evidence, citing the discovery of emails on a laptop used by a top Clinton aide. Justice Department officials warned Comey against sending the letter, saying that doing so would be inconsistent with department policy meant to avoid the appearance of prosecutorial interference or meddling in elections.
Oct. 28, 2016: Trump reacts to FBI's decision to investigate new messages related to Clinton's emails, telling a campaign rally that he has "great respect for the FBI for righting this wrong."
Nov. 6, 2016: Comey tells Congress in a follow-up letter that a review of newly discovered Clinton emails has "not changed our conclusions" that she should not face criminal charges.
Nov. 6: Trump criticizes Comey's second letter to Congress, saying Clinton was being protected by a "rigged system" and pronouncing her "guilty," despite the FBI's conclusion that criminal charges were unwarranted.
Nov. 8, 2016: Trump is elected president.
Nov. 12, 2016: During a telephone call with top campaign donors, Clinton blames Comey for her defeat by Trump. Clinton said her campaign was on track to win the election until Comey sent the letter to Congress on Oct. 28.
Nov. 13, 2016: In a CBS "60 Minutes" broadcast after the election, Trump said he hadn't decided whether to keep Comey.
Jan. 6, 2017: Comey is among a group of four top U.S. intelligence officials who briefed then-President-elect Donald Trump on their conclusions that Russia meddled in the presidential election on his behalf. Trump told The Associated Press by telephone after the meeting that he "learned a lot" but declined to say whether he accepted their conclusion about Russia.
Jan. 22, 2017: Two days after taking office, Trump appears to single out Comey at a White House reception to thank law enforcement officers and others that helped during the inauguration. Trump called Comey over to where he was standing in the Blue Room to offer a handshake and a partial hug, then commented that Comey has "become more famous than me."
March 8, 2017: During a cybersecurity conference at Boston College, Comey said he planned to serve his entire 10-year term, quipping, "You're stuck with me for another 6½ years."
March 20, 2017: Comey testifies to Congress that the FBI has been investigating possible links between Trump associates and Russian officials since July, the same month he held an unusual news conference to discuss the investigation into Clinton. Comey had previously refused to acknowledge the parallel Trump investigation, and his disclosure enrages Democrats who already blamed Comey for costing Clinton the presidency.
March 20, 2017: Comey testifies at the same hearing that the FBI and Justice Department have no information to substantiate Trump's unsubstantiated claim on Twitter that former President Barack Obama wiretapped him before the election.

May 3, 2017: Testifying before the Senate Judiciary Committee, Comey insists that he was consistent in his handling of the separate investigations into Clinton and Trump. Comey also said it made him feel "mildly nauseous" to think his actions in October might have influenced the election outcome. But he told senators: "I can't consider for a second whose political futures will be affected and in what way. We have to ask ourselves what is the right thing to do and then do it."
May 9, 2017: Comey sends Congress a letter correcting his prior sworn testimony regarding emails handled by longtime Clinton associate Huma Abedin. Comey had told Congress that Abedin had sent "hundreds and thousands" of emails to her husband's laptop, including some with classified information. The two-page, follow-up letter said that, in fact, only "a small number" of the thousands of emails found on the laptop had been forwarded there while most had simply been backed up from electronic devices.
May 9, 2017: Trump abruptly fires Comey. "It is essential that we find new leadership for the FBI that restores public trust and confidence in its vital law enforcement mission," Trump states in a letter addressed to Comey.
May 10, 2017: Trump told Russian officials during an Oval Office meeting that firing Comey helped to deescalate the investigation into his ties with the Kremlin, The New York Times reported on May 19.

May 11, 2017: The New York Times reports on a dinner Comey had with Trump a week into his term in which the president asked him “do I have your loyalty?” Comey did not oblige but promised his honesty instead, according to the Times, which cited two Comey associates. The White House disputed the account.
In an interview with NBC News anchor Lester Holt, Trump revealed that he planned to fire Comey even before receiving a recommendation to do so from his attorney general. He alleged the FBI was in turmoil under Comey's leadership, and described him as a "showboat" and "grandstander." He also suggested the Russia investigation played a role in the firing. "When I decided to [fire Comey], I said to myself, I said you know, this Russia thing with Trump and Russia is a made up story," he said.
May 12, 2017: "James Comey better hope that there are no 'tapes' of our conversations before he starts leaking to the press!" Trump tweets.

Flynn. “I hope you can let this go,” the president said, citing an unclassified memo from Comey. The Times said it did not received the memo but its reporter was read parts of it by Comey's associates.

June 8, 2017: Comey testifies to the Senate intelligence committee that he believes his involvement in the Russian investigation is what led to his firing. He said President Trump pressured him to to drop an investigation into one of his senior advisers, fired him after he would not do so and lied about the affair.

Trump’s lawyer responded by denying the president pressured Comey and accused the former FBI director of leaking “privileged information.”
