As part of their broader effort to discredit Comey, Trump and his defenders have seized on a portion of Comey's Thursday testimony before the Senate Intelligence Committee in which he said he allowed a friend to share with the press contents of a memo detailing his conversation with Trump in the hope that it would trigger the appointment of a special prosecutor.
Comey said he felt uncomfortable with the president's pressure to drop an investigation into Michael Flynn, Trump's first national security adviser.
Trump on Friday said Comey's testimony showed "no obstruction".
Meanwhile, the House Intelligence Committee asked on Friday for Comey's memos to be handed over, and separately sent a letter to the White House demanding any "recordings or memoranda" of conversations with Comey that Trump or the White House may or may not possess.
"That was an excuse by the Democrats who lost an election that some people think they shouldn't have lost, because it's nearly impossible for the Democrats to lose the Electoral College, as you know", Trump said.
During nearly three hours of statements Thursday before the Senate Intelligence Committee, Comey described himself as "stunned" by Trump's "very disturbing" and "very concerning" behavior towards him. The former Federal Bureau of Investigation director's testimony before the Senate Intelligence Committee on Thursday was a feast of contradiction and self-serving showmanship. "What's most important is that investigators in the Senate and at the Department of Justice get all the facts and find the truth", Murphy said.
On Thursday, Comey said he could not discuss why he thought Attorney General Jeff Sessions would recuse himself from the Russian investigation in an open hearing.
He also accused Qatar, a key US military partner, of funding terrorism "at a very high level", and said solving the problem in the tiny Persian Gulf nation could be "the beginning of the end of terrorism".
When a reporter asked about Comey, Trump again said he never asked for the Justice Department's Russian Federation probe to be dropped - an act that experts say could constitute an obstruction of justice.
'Who would ask a man to pledge allegiance under oath?
"And he said multiple times that he choose to take detailed notes about his interactions with Trump because he anxious the White House and President would lie about them if he didn't".
"As I used to say to juries when I talked about a witness, you can't cherry pick it".
"I found him to be credible, candid and thorough", Collins said of Comey on MSNBC's "Morning Joe".
Trump replied: "Oh, you're going to be very disappointed when you hear the answer, don't worry".
"Today we reaffirm and celebrate our strategic partnership that began more than 20 years ago", Trump said.
QUESTION: He did say under oath that you told him to let the Flynn - you said you hoped the Flynn investigation, he could let go.
When Trump asked him to drop the Flynn investigation, Comey demurred and simply agreed Flynn was a "good guy".
