President Donald Trump's lawyer Marc Kasowitz took a victory lap Thursday following the blockbuster testimony of fired FBI Director James Comey, saying the much-anticipated Senate hearing proved what the White House has been saying for months.

And he hammered Comey for releasing information about his conversations with the president to reporters in an attempt to force the appointment of a special-counsel inquest into Russian election interference.

'Today, Mr. Comey admitted that he unilaterally and surreptitiously made unauthorized disclosures to the press of privileged communications with the President,' Kasowitz said in a statement.

And 'contrary to numerous false press accounts leading up to today's hearing,' he added, 'Mr. Comey has now finally confirmed publicly what he repeatedly told the President privately: The President was not under investigation as part of any probe into Russian interference.'

Marc Kasowitz, the personal lawyer for President Donald Trump, delivered a walloping statement Thursday aimed at fired former FBI director James Comey

Comey admitted in his Senate testimony on Thursday that the president was never an investigative target, and said he had asked a friend to leak portions of his notes to the press

'Mr Comey's testimony also makes clear that the President never sought to impede the investigation into attempted Russian interference in the 2016 election,' Kasowitz claimed.

Kasowitz, the president's outside counsel who is responsible for looking after his personal interests – not those of the presidency – delivered his statement in writing and orally following the former FBI director's testimony to the Senate Intelligence Committee.

The smallish gathering at the National Press Club who heard him speak in person was an unconventional coda to an unprecedented day that saw the White House forced to deny Trump is a liar.

Kasowitz instead called Comey a liar, calling into question the memos that comprised the bulk of his testimony.

Trump 'never pressured Mr. Comey,' he insisted.

And 'the President also never told Mr. Comey, "I need loyalty, I expect loyalty" in form or substance.'

Both claims were part of Comey's written and oral presentations.

Kasowitz read his statement and left the podium without taking questions.

Trump kept a low online profile Thursday, not tweeting at all, but delivered a speech to a Christian evangelical group in which he never mentioned Comey

Kasowitz said 'the appropriate authorities' would have to determine if Comey's own orchestrated press leak should be investigated

Comey declared Thursday that the White House defamed him, and that he wrote detailed memos about his conversations with the president as a hedge against Trump lying about their discussions in the future.

'I can definitively say that the president's not a liar, and I think it's frankly insulting that that question would be asked,' White House spokeswoman Sarah Sanders told reporters.

Her short press briefing was sandwiched in between Comey's public hearing and a private classified session with the senators.

Also in the lunch hour, Trump himself delivered a speech to a Christian evangelical group, declaring that Americans 'don't worship government – we worship God.'

Kasowitz sought to place blame on Comey, especially for his embarrassing revelation that he leaked parts of a private memo on a conversation with Trump to reporters through a third party – a law professor friend.

He referred to Trump's talks with Comey as 'privileged' four times, without acknowledging that the White House declined to assert a claim of executive privilege over any of those conversations before Comey testified.

Comey testified, Kasowitz recounted, 'that immediately after he was terminated he authorized his friends to leak the contents of these memos to the press in order to "prompt the appointment of a special counsel".'

The fired former FBI director called the White House and the president liars on several occasions Thursday

Kasowitz left a small briefing room at the National Press Club in Washington without taking questions from reporters

'Although Mr. Comey testified he only leaked the memos in response to a tweet, the public record reveals that the New York Times was quoting from these memos the day before the referenced tweet, which belies Mr. Comey's excuse for this unauthorized disclosure of privileged information and appears to entirely retaliatory.'

'We will leave it the appropriate authorities to determine whether this [sic] leaks should be investigated along with all those others being investigated,' he said.

Kasowitz had already weighed in Wednesday evening, after the Senate committee released Comey's written testimony a day ahead of his public hearing.

That account confirmed that Comey had told Trump on three separate occasions that he wasn't the target of any FBI investigation.

'The president is pleased that Mr. Comey has finally publicly confirmed his private reports that the President was not under investigation in any Russia probe,' Kasowitz wrote Wednesday.

'The president feels completely and totally vindicated.'

Thursday's statement began less confidently, with Kasowitz misspelling the word 'president.'

'I am Marc Kasowitz,' he wrote, 'Predisent Trump's personal lawyer.'

Kasowitz also misspelled the last name of Dan Coats – his statement rendered it 'Coates' – who is the director of national intelligence.
