President Donald Trump tweeted Friday morning that James Comey's testimony gave him "total and complete vindication," and he accused the former FBI director of lying under oath.

"Despite so many false statements and lies, total and complete vindication," he tweeted. "..and WOW, Comey is a leaker!"

Trump's tweet echoes the statement made by his personal attorney Thursday afternoon, essentially accusing Comey of committing perjury in his sworn testimony before the Senate intelligence committee on Thursday.

Attorney Marc Kasowitz said Comey was not telling the truth when he testified that Trump had demanded loyalty from Comey and had asked him to drop an investigation into former National Security Adviser Michael Flynn.

But Kasowitz simultaneously cheered Comey's confirmation that he had told Trump that Trump was not personally under investigation by the FBI and said his testimony "makes clear that the president never sought to impede the investigation into attempted Russian interference in the 2016 election."

Comey, however, testified that he felt pressured to drop the investigation into Flynn, who is under scrutiny for accepting payments tied to Russia and Turkey and communicating with Russian officials.

Comey stopped short of saying he believed Trump meant to obstruct justice, instead saying that determination would be left up to special counsel Robert Mueller, who was appointed last month by Deputy Attorney General Rod Rosenstein to take over the FBI's investigation into Russia's election meddling.

The former FBI director revealed Thursday that he had given a friend the contents of memos he made following his meetings and phone calls with the president, who turned them over to a New York Times reporter.

In his statement Thursday, Kasowitz accused Comey of leaking privileged information and called for the "appropriate authorities" to determine whether his actions should be investigated.

With Trump and Comey accusing one another of lying about the nature their interactions leading up to Comey's May 9 dismissal, the pressure for the White House to produce any recordings of their conversations has intensified.

"Lordy, I hope there are tapes," Comey said during Thursday's hearing.
