Trump said he would be happy to testify under oath that he had not told Comey he expected loyalty from him, and had not pressed Comey to end the FBI's investigation of former National Security advisor Michael Flynn.
In his testimony Thursday, former FBI Director James Comey's statement about leaking information of private conversations he had with President Donald Trump revealed the special counsel investigation led by Robert Mueller was "poisoned fruit", stated former House Speaker Newt Gingrich.
The reporter then asked if Trump would be willing to speak under oath, as Comey did, to give his version of the events.
KARL: Always fair. Mr. President, I want to get back to James Comey's testimony. No, I didn't say that and I didn't say the other.
Trump concluded the morning tweets with an attack on Democrats, calling them "obstructionists". "I didn't say that", Trump said. "Who would ask a man to pledge allegiance under oath?" he said. "You have to run up the whole East Coast and you have to win everything as a Republican, and that's just what we did", Trump said.
While testifying before the Senate Intelligence Committee on Thursday, Comey, in his opening statement, said the president had privately told him in the Oval Office, "I hope you can see your way clear to let this go, to letting Flynn go. Think of that. I hardly know the man".
"Well, I'll tell you about that maybe sometime in the very near future", Trump said, according to the AP.
The White House has seized on Mr Comey's confirmation that Mr Trump personally was not under investigation over his ties to Russian Federation to declare a victory of sorts.
"I didn't say that", Trump said again. "Our judgment, as I recall, was that he was very close and inevitably going to recuse himself for a variety of reasons", Comey said during his questioning.
"There's no - 'Hey, I'm hoping - You and I are friends". Mike Conaway (R-TX) and Adam Schiff (D-CA) wrote to Comey in the wake of the testimony, requesting "any notes or memoranda in his possession memorializing discussions Comey had with President Trump". "I'm not hinting anything".
He hinted again that he had tapes of his private talks with the former Federal Bureau of Investigation chief that would disprove Mr Comey's account, but declined to confirm the existence of any recordings.
Shortly after the press conference, leaders of the House Intelligence Committee said they had asked the White House whether there were any such tapes.
