Asked Tuesday about the testimony, President Donald Trump was tight-lipped: "I wish him luck", he told reporters.
It was in that conversation that Trump asked Comey to end the investigation into Flynn, and encouraged him to investigate leaks, the people said.
The White House had hoped to set up a "war room" stocked with Trump allies and top-flight lawyers to combat questions about the FBI and congressional investigations into possible ties between the campaign and Russian Federation.
Coats says he has never been pressured or felt pressure to intervene in shaping intelligence products. "For the reasons discussed above, I did not mention that the President broached the FBI's potential investigation of General Flynn".
Comey, in one of his last appearances in front of Congress before being fired, misstated the number of potentially sensitive emails that were found on a laptop in the possession of former Congressman Anthony Weiner, the estranged husband of Hillary Clinton aide Anthony Weiner.
"He said he had nothing to do with Russia, had not been involved with hookers in Russia, and had always assumed he was being recorded when in Russia". Network television stations will live broadcast the hearing.
Mr Comey is set to testify before the Senate Intelligence committee on Thursday. Rubio's approach to questioning Comey could be a bellwether for how hard Republicans will focus on the former Federal Bureau of Investigation director's own conduct versus Trump's. But it is not clear what, if anything, Comey told the president about whether he was being investigated.
"That was true; we did not have an open counter-intelligence case on him".
Comey's testimony may also clarify other supposed misunderstandings. "During our one-on-one meeting at Trump Tower, based on President-Elect Trump's reaction to the briefing and without him directly asking the question, I offered that assurance". Comey says Trump told him, "I hope you can let this go".
Comey said he was so unnerved by the conversation that immediately after the dinner he wrote down the comments in a memo. There were nine total conversations between the two men over the course of four months: three in person and six on the phone. Comey appears before the same committee on Thursday.
Comey said Trump told him at a dinner on January 27, a week after the president took office, that: "I need loyalty". Trump then said "He said he would do that and added, 'Because I have been very loyal to you, very loyal; we had that thing you know.' I did not reply or ask him what hemeant by 'that thing'".
According to Comey, Trump told him he was considering ordering an investigation into the salacious allegations the FBI director had briefed him on in the January 6 meeting at Trump Tower.
Comey only replied: "'I agree he is a good guy", according to the memo.
Because of the nature of a high-profile Congressional hearing, Comey will be asked to repeat multiple things that are already widely known. The president frequently calls the story "fake news" and "made up".
He also described two other meetings with Trump - the January 6th intelligence briefing where he provided details about the salacious Russian Federation dossier and a February 14th Oval Office meeting - along with two phone calls he had with the president.
Senators want to question Comey about reports Trump urged him to stop investigating Michael Flynn, his ousted national security adviser, in the FBI's probe of Russian interference in last year's election.
