The changing rationales the White House offered added an element of chaos to the president's action. Trump wrote on Twitter Friday morning.
The White House has issued a denial of the allegation. And it comes at a particularly precarious time for the Trump administration as it searches for someone to nominate to succeed Comey as the next leader of the FBI - the official who will take over investigations into Russian interference in the 2016 election and any coordination between Trump associates and Russian officials.
Of course, keeping people guessing may well be the way the president wants to play it. He leans heavily on daughter Ivanka Trump and son-in-law Jared Kushner, as well as Hope Hicks, his trusted campaign spokeswoman and Keith Schiller, his longtime bodyguard.
Comey's friends immediately started leaking to reporters that the former top cop was "not anxious about any tapes" of talks between him and the president.
He also said the "assault" on American institutions was not limited to Trump.
Preparations for the trip come as Trump's inner circle appears to be shrinking, fueling paranoia inside the West Wing among a tired staff battered by a drumbeat of reports suggesting some senior staffers are on the chopping block. But Comey's firing triggered a new wave of Russia-related turbulence.
It may prove to be the most consequential of all of Donald Trump's tweets.
Mr Trump told reporters that "we could make a fast decision" because "almost all of them are very well known". The White House said the event had caused a loss of trust and Flynn resigned.
Mr. Trump, who has sought better relations with Russian Federation, has continued to question whether Russian Federation was behind the hacking of email accounts belonging to Democrats involved in Hillary Clinton's 2016 presidential campaign.More news: Taylor Swift using disguises to hide new romance
Republicans control both chambers of the U.S. Congress.
Much of Trump's ire has been focused on the communications team, all of whom were caught off guard by Comey's ouster.
White House press secretary Sean Spicer repeatedly refused to say Monday whether President Donald Trump is secretly recording his conversations.
Mr Cornyn is the second-ranking Senate Republican and a strong defender of Mr Trump, a president who often places a premium on loyalty.
In a valuable article on Lawfare's blog posted May 11, professor Bob Bauer of the New York University School of Law, who was White House counsel to President Obama, explained how Trump's firing of Comey, who headed the Russian investigation, violated norms or standards governing federal criminal prosecutions.
Trump says in the Oval Office that the administration is working to quickly find a successor to Comey.
The former USA attorney for the Southern District of NY urged public servants to "say no to the President". "He's a little bit like a quarterback that gets ahead of his offensive line". "Now, I don't know what fully was in the president's mind, but I do know this". Aides were also eager for Trump's first foreign trip, a high-stakes blitz through the Middle East and Europe. "You're certainly getting close to Republicans on the Hill probably starting to assess how to move policy with a White House that is, to quote Sen".
"That's, frankly, offensive", Spicer said.
