Mr Trump also defended his media team over criticism at their handling of this week's event - and threatened to abandon the policy of holding daily press briefings. Sarah Huckabee Sanders, the deputy press secretary, filled in for him.
When I did this now, I said I probably maybe will confuse people. He simply stated a fact.
Legal experts expressed concerns about the implications of Trump's tweet. Did Trump or anyone else ask for a justification to fire Comey or for you to write the memo?
"I think the president wants loyalty to this country and to the rule of law", he said.
"The president should immediately provide any such recordings to Congress or admit, once again, to have made a deliberately misleading - and this case threatening - statement", said Schiff.
Before Comey was relieved of his duties, the president insists that the FBI director told him he was not under investigation for any kind of collusion with Russian Federation.
Despite insisting that there was no wrongdoing by the Trump campaign in regard to Russia, Trump said that he wanted things to be "absolutely done properly".
In a letter to his former colleagues, Comey said, "I have long believed that a President can fire an FBI Director for any reason, or for no reason at all".
On Wednesday, Trump said Comey was let go because he "wasn't doing a good job".
But the president told NBC News on Thursday that he was going to can Comey even without their recommendations.
IL 8th District Congressman Raja Krishnamoorthi has requested President Donald Trump turn over to the House Oversight Committee any recordings of conversations with recently fired FBI Director James Comey.
That explains why Trump decided himself to fire Comey because of pique over "this Russian Federation thing", as he told NBC Nightly News anchor Lester Holt on Thursday. Comey hasn't made similar comments publicly. Trump tweeted on Friday.
Not only was this a loosely veiled threat directed at the former FBI director, whom Trump unceremoniously fired on Tuesday, but it also suggested that Trump possessed recordings of their conversations-perhaps even a tape of their January 27 dinner, where the president claims Comey told him he was not under investigation as part of the bureau's probe of the Trump campaign's Russian Federation ties.
McCabe's hearing came after Comey was unexpectedly fired by US President Donald Trump on Tuesday evening. Instead, Trump's worst instincts were enabled by everyone around him.
"They've been vetted over their lifetime, essentially", he said of the candidates, describing them as "very well-known, highly respected, really talented people", before adding: "And that's what we want for the Federal Bureau of Investigation".
