"I never was insane about Trump", J. Brien Comey told USA Today's affiliate in North Jersey.
Politico on Friday reported, citing several unnamed sources close to Trump, that after Flynn left the White House in February, the President said he should have kept Flynn on.
The Justice Department on Friday issued a transcript of Rosenstein's remarks.
Comey also agreed to testify before the Senate Intelligence Committee in an open, public hearing.
In pointing out how ridiculous he thinks the impeachment rumors are, Trump tweeted, "With all of the illegal acts that took place in the Clinton campaign & Obama Administration, there was never a special counsel appointed!" Following Trump's comments, experts and analysts said the president's actions could be bigger than Watergate and may have placed him in impeachment territory.
Apparently, a few days later, Trump allegedly demanded loyalty from Comey at a private White House dinner, during which the POTUS asked him twice to pledge loyalty to him as the new commander-in-chief.
The White House has been thrown into turmoil by a succession of stunning allegations against the president this week, including that he may have obstructed justice by asking Comey to drop an investigation into one of his top advisors.
"The committee looks forward to receiving testimony from the former Director on his role in the development of the Intelligence Community Assessment on Russian interference in the 2016 U.S. elections, and I am hopeful that he will clarify for the American people recent events that have been broadly reported in the media", Burr said.
Trump also later admitted that the ongoing Russian Federation investigation and possible ties between his campaign associates also played a role in his decision to fire Comey. "I believe it. I stand by it".
Trump has reacted furiously to the appointment of a special counsel, a prosecutor with wide authority to investigate Russia's interference and other potential crimes uncovered.
Deputy Attorney General Rod Rosenstein was returning to the Capitol on Friday for another closed-door session, this time with all members of the House. "The investigation would have always continued, and obviously the termination of Comey would not have ended it". However, at a combative news conference Thursday, he fell short in trying to resolve questions about investigations into his campaign and his first four months in office.
Despite initially opposing appointment of an independent counsel, Republican House Speaker Paul Ryan said on Thursday that the development "helps assure people and the Justice Department that they're going to go do their jobs independently and thoroughly, which is what we've called for all along".
