WASHINGTON -- Former FBI director James Comey testified Thursday that he orchestrated the leak of his accounts of conversations with President Donald Trump because he thought it might lead to the appointment of a special prosecutor to lead the Russia investigation.
In one of the most revealing moments of a blockbuster Senate intelligence committee hearing, Comey said he had asked a friend at Columbia University to leak the content of one of his memos.
He said it dawned on him that there could be corroboration of a memo that he wrote after the president tweeted that he better hope there were no White House tapes of their conversations.
"My judgment was that I needed to get that out into the public square," he said.
He added he took the step "because I thought that might prompt the appointment of a special counsel."
Comey at one point told Senators, "Lordy, I hope there are tapes."
Comey was asked by Arkansas Sen. Tom Cotton whether he believed that Trump had colluded with the Russians.
"It is a question I don't think I should answer in an open setting," Comey said, adding the question would be answered by special counsel Robert Mueller's investigation.
Comey also testified the Trump administration "chose to defame me," told "lies, plain and simple" and that he was "confused" by Trump saying he was fired because of the Russia probe.
"The administration chose to defame me and, more importantly, the FBI by saying the organization was in disarray ... those were lies," Comey said.
However, he also said he did not believe that either Trump nor his staff had asked him to stop the Russia investigation.
He told the committee the "shifting explanations" from the White House for why Trump fired him last month "confused" and increasingly concerned him.
At the White House, deputy press secretary Sarah Huckabee Sanders pushed back on the idea that Trump was a liar.
"I can definitely say the president is not a liar, and I think it's frankly insulting that question would be asked," she said, pushing back on Comey's testimony that he was worried the president would not tell the truth about their meetings.
Comey also revealed new details about his meeting with Trump during the transition when he briefed the president-elect on details of a salacious dossier drawn up by a former British spy that suggested Russia had incriminating information about him.
Comey said he didn't want to create a "J. Edgar Hoover-type situation" in which Trump concluded the bureau was trying to hold something over him. He said he was keen to leave the impression with Trump that the FBI was not investigating him.
Comey said he took exception to White House claims that the FBI was in disarray and that it was poorly led and had lost confidence in his leadership.
"Those were lies, plain and simple, and I am so sorry that the FBI workforce had to hear them, and I am so sorry that the American people were told them," Comey said.
Comey seized center stage in a compelling national political drama as he testified that as soon as he met the president-elect during the transition, he decided to create a written record of their meetings.
"I was honestly concerned that he might lie about the nature of our meeting," Comey said.
Comey said he knew that one day he might need a written record of their conversations to defend himself and the FBI.
Comey said he believed it was his right to publicize the details of what he viewed were unclassified recollections of his conversation with Trump in his role as a private citizen.
He said he asked his friend to take the action rather than doing it himself because the press was camped outside his house and it would have been like feeding "seagulls at the beach."
He also revealed he had given all the memos to Mueller.
Comey said he took the president's expression of "hope" that he could ease off of Flynn as a directive.
He said it rang in his ears as "will no one rid me of this meddlesome priest," paraphrasing a quote attributed to English King Henry II that courtiers took to mean he wanted the Archbishop of Canterbury Thomas Becket murdered in 1170.
Comey said it had never occurred to him that there might be tapes of his conversations with Trump until the president tweeted about it.
And he called on Trump to make them public if tapes do exist.
"If he did, my feelings aren't hurt ... release all the tapes," he said.
Comey walked into the hearing room, wearing a dark suit and red tie, and sat impassively while a phalanx of press photographers crowded in front of him to take his picture. He sat alone at the witness table, facing the committee senators.
Republican Senate intelligence committee Chairman Richard Burr promised that the panel would establish the "facts separate from rampant speculation" and lay them before the American people so the nation could move on from the drama over alleged Russian interference in last year's election.
Trump's camp was reacting in real time to Comey's testimony, which was being carried on network television as well as streamed on multiple mobile devices in a rare moment of common national experience in the Internet age.
An administration official said the president would monitor the hearings from a White House dining room in between meetings.
A person close to Trump's legal team said the president "disputes ever saying that he wanted Comey's loyalty or to drop the case against Michael Flynn."
His testimony represents a pivotal moment in the saga of Russian election hacking and alleged collusion by Trump aides that has cast a dark shadow over the opening months of the new administration.
Comey also said he was disturbed the president repeatedly raised the issue of his wanting to keep his job and interpreted it as a sign that the president hoped to get something in return.
He also revealed the words Trump whispered in his ear, when the president summoned him across the room on camera at a reception at the White House shortly after the inauguration.
"What the president whispered in my ear was, 'I really look forward to working with you,'" Comey said.
Comey related his sense of foreboding when he was asked by Trump to remain behind after after a wider meeting of White House and national security officials in the Oval Office.
"I knew something was about to happen, that I needed to pay very close attention to," Comey said, explaining why he decided to keep a close record of the meeting.
He also said he believed Attorney General Jeff Sessions knew something significant was about to happen, and Trump's son-in-law picked up on it too.
Republican Sen. Jim Risch of Idaho sought to water down the impact of Comey's testimony that Trump had told him that he hoped he would go easy on Flynn in the Russia investigation.
He stressed that according to Comey, Trump had said he "hoped" for Flynn to be let go, and had not specifically ordered Comey to take that course.
But Comey replied "I took it as this is what he wants me to do."
Comey's penchant for making a theatrical splash has already turned what was set to be a one-day drama into a two-day feeding frenzy, after he released his prepared opening statement Wednesday afternoon, transfixing Washington.
