Federal Bureau of Investigation chief's unceremonious ouster boomerangs on Trump

Comey kept memos of conversations he had with the president, the Times reported.

Elijah Cummings, top Democrat on a key House oversight panel, countered that Mr Ryan and the Republicans had shown "zero, zero, zero appetite for any investigation of President Trump". When their sources are investigated, journalists face the prospect of surveillance or subpoenas to testify and it can inhibit important investigative reporting.

Walorski says in a statement she hopes Comey will testify before the committees. "I don't know that you could say the same about the president". Just a few days earlier, Trump fired Comey under suspicious circumstances. "I don't think we should rush to that conclusion".

"If he substituted his judgement for Comey's under circumstances where he would try to make it look like Flynn was being cleared but he was actually orchestrating it, to me... the key word in the statute of obstruction to justice is 'corruptly.' What corruptly means is you have to understand that what you're doing is a violation of the law and you have to do it with a specific goal to subvert an ongoing investigation".

Comey's memo, an apparent effort to create a paper trail of his contacts with the White House, would be the clearest evidence to date that the president has tried to influence the investigation.

The cloud hanging over the White House mushroomed in February when Trump's national security adviser Michael Flynn resigned over concerns about his meetings with Russia's ambassador in Washington. The associate who described the memo said Comey is willing to testify but wants to do it in public to ensure a full airing of events.

House Republicans have mixed reactions to the surprise announcement that the Justice Department has appointed former FBI Director Robert Mueller as a special counsel to oversee a federal investigation into possible collusion between Russian Federation and the Trump campaign in 2016.

"While the president has repeatedly expressed his view that General Flynn is a decent man who served and protected our country, the president has never asked Mr. Comey or anyone else to end any investigation, including any investigation involving General Flynn", the White House statement said.

"This daily dose of controversy, of scandal, of instability, is bad for the government and I think it's also very taxing on the American people", he said.

Pressure on Republicans for stronger action has grown amid reports that Trump asked now-fired FBI Director James Comey to drop an investigation into former White House national security adviser Michael Flynn and gave classified information to Russian officials. Spicer told the gaggle that that Trump recently spoke with Israeli Prime Minister Benjamin Netanyahu, but he insisted that it was about Trump's upcoming trip overseas, and not about how Trump's leaked intelligence reportedly came from the Israelis. Framing political crises as law enforcement matters "has the effect at the end of the day of leaving people with less respect for the legal process than before". The White House disputed the account. Rep. Jason Chaffetz (R-Utah), the chairman of the House Oversight Committee, said he had scheduled a hearing for next Wednesday, May 24 with Comey. He called for the appointment of a special prosecutor to investigate.

The FBI and several congressional panels are probing allegations of collusion between Trump's team and Russian Federation, something the president flatly denies.

Rep. Jason Chaffetz, Republican chairman of the House oversight committee, sent a letter to the Federal Bureau of Investigation on Tuesday requesting that it turn over all documents and recordings that detail communications between Comey and Trump. Ryan backed Chaffetz's request. Putin made light of the matter at a news conference in Russian Federation, saying Moscow was ready to hand a transcript of the meeting to USA lawmakers if that would help reassure them.
