The bombshell Comey news came as the beleaguered administration was still struggling mightily to explain Monday's revelation that the president had disclosed highly classified information to the Russian foreign minister and the country's ambassador to the United States.
Trump removed Comey in the middle of a Federal Bureau of Investigation probe into alleged Russian interference in the the 2016 US presidential election, and possible ties between Trump's campaign and Russia. "We need the facts", Ryan said.
"And he said that ever since, the president had been trying to be chummy in a fashion that Comey felt was created to absorb him into Trump's world - to make him part of the team".
"I think we've seen this movie before", the Arizona Republican said at a dinner to receive the International Republican Institute's Freedom Award.
The House Oversight and Government Reform Committee invited Comey to testify next Wednesday. "They're going to pay a big price for leaking", Trump told members of the U.S. House of Representatives in February. "I'm a person who wants to get the facts". They made the recommendation over the former FBI director's handling of the investigation into Democratic presidential candidate Hillary Clinton's private email server.
Comey told Trump he should not contact him directly about FBI investigations but follow procedure and have the White House counsel ask the Justice Department, which oversees the FBI, the Times reported. The Trump administration, along with Russian Federation, has denied the accusation. Comey wrote the memo after he met in the Oval Office with Trump, the day after the president fired Flynn on February 14 for misleading Vice President Mike Pence about the extent of his conversations previous year with Russia's ambassador, Sergei Kislyak.
The Wisconsin Republican was asked on his way out of a news conference whether he still had confidence in Trump, and he responded, "I do".
Republicans, frustrated by the president's relentless parade of problems, largely sought to cool the heated climate with assurances they would get to the bottom of scandals.
The White House disputed Comey's account of the February conversation concerning Flynn, but did not offer specifics.
Ryan declined to wade into whether Trump obstructed justice - a crime under USA law. An increasing number of Republicans, too, have joined in calling for Congress to dig deeper, especially after Trump fired FBI Director James Comey who had been leading the bureau's probe.
Trump is preparing to leave town Friday on his first foreign trip, and aides have been hopeful the journey will be a chance for the administration to get back on track after weeks of chaos and distractions.
Under current U.S. law, the president has the power to declassify information as he or she sees fit.
"We need to have immediate classified briefings on what occurred at this meeting so that Congress can at least know as much as Russian leaders", she said in a statement.
"The last thing I'm going to do is pre-judge anything", he said said during the news conference at the Republican National Committee.
Asked by reporters whether he thought the allegations against Trump were grounds for impeachment, Republican Representative Justin Amash said, "If the allegations are true, yes". It also asked acting FBI Director Andrew McCabe to give the committee any notes Comey might have made regarding discussions he had with White House or Justice Department officials about Russia's efforts to influence the election.
