After a day of Twitter silence, President Donald Trump responded Friday morning to former FBI Director James Comey's bombshell Senate testimony.

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

In public statements to the Senate Intelligence Committee, Comey on Thursday testified under oath that he had come to believe that Trump fired him "because of the Russia investigation" into whether the Trump campaign colluded with Russia to meddle in the 2016 election. Comey also said he wrote memos following meetings with the president because he was afraid Trump would lie about the nature of them.

Comey, whom Trump fired on May 9, also said the Trump administration tried to defame him as well as the FBI by describing the bureau as being in disarray at the time of his dismissal. Comey described statements like that as "lies, plain and simple."

Trump's claim that Comey "is a leaker" appears to stem from an acknowledgement by the former FBI director on Thursday that he instructed a friend to leak to the news media the content of the memos about his meetings with Trump. Comey said he did so to help spur the appointment of a special counsel to lead the Russia investigation.

Trump's personal attorney Marc Kasowitz suggested Thursday that Comey lied under oath and accused him of making "unauthorized disclosures" to the press.

At least one major Democrat was quick to suggest that Trump's tweet implied Comey lied under oath.

"Making a false statement to Congress is a felony," Sen. Brian Schatz tweeted. "This is not just another silly tweet."
