But he left aside scathing testimony by Comey, who was sacked in early May, that Trump had tried to derail a probe into his onetime national security advisor - at best, a political miscalculation by a tradition-shredding president, and at worst, a criminal obstruction of justice. But he had no fewer than nine conversations with Donald Trump in four months and knew he had to record the details afterwards. "Who would do that?"
House Speaker Paul Ryan told reporters Thursday that Trump "is new at this, new to government", adding that he probably "wasn't steeped in the long running protocols that established the relationships between the Department of Justice, the Federal Bureau of Investigation and White Houses".
"Some of the things that he said just weren't true", added the president, who - when asked if he would be willing to speak under oath to special prosecutor Robert Mueller about the encounters - responded: "100 percent".
Mr Comey told Congress under oath he believed he was sacked to influence his investigation into the Trump campaign. In the hearing, Comey did not disclose any links between Trump advisers and alleged Russian meddling.
President Donald Trump said Friday he is willing to testify under oath about his interactions with former FBI Director James Comey and accused the latter of being untruthful during his testimony in Capitol Hill on Thursday.
Trump has come out with a tweet early Friday: "Despite so many false statements and lies, total and complete vindication. and WOW, Comey is a leaker".
Comey said Thursday the president's tweet that said Comey "better hope that there are no "tapes" of their conversations had compelled him to share a memo he wrote. 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.
Media coverage of the hearing was biased against Trump and highly sympathetic and uncritical towards Comey, Rowley commented. "Now I did not obey that but that is the way I took it", Comey testified.
The president also recirculated another defence of his actions posted on Twitter by Alan Dershowitz, a Harvard Law School professor emeritus who has advised the Trump team on Middle Eastern policy.
"There might be corroboration of our conversation, there might be a tape", Comey said.
Democratic Senator Joe Manchin of West Virginia asked Comey the key question: "Do you believe this rises to obstruction of justice?" Those conversations are reflected in memos Mr Comey wrote, and now are in the possession of Robert Mueller, the special counsel in the Russian Federation probe named after Comey's firing.
When Karl asked about the so-called "loyalty pledge" that Comey referred to, Trump denied that it ever occurred, saying "I hardly know the man, what kind of person would do that?"
