Other advisers joined the discussion, with a goal of presenting the President with a plan for outside legal counsel as the Russian Federation investigation enters a new and potentially perilous phase for the White House.
The revelation that Mr Trump may have asked his FBI director to stop investigating a member of his staff who had been the subject of scandal for misrepresenting conversations he had with Russian officials during the transition period, was seen as one of the clearest signs that Mr Trump had tried to directly influence investigations by the Justice Department and the FBI.
On the subject of the allegations - started in July 2016 by the Hillary Clinton campaign and embraced by Democrats and some of the media since her surprise defeat in November - that he and his campaign colluded with Russia, Trump said that "the entire thing has been a witch hunt". "Everybody thinks so", Trump said. President Donald Trump was about to get the question - the one he'd avoided for almost 48 hours but could no longer.
"Trump feels really, really, really, bad about firing him, and he genuinely thinks if the investigation is over Flynn can come back", a White House official told The Daily Beast.
The broad federal probe under Mueller, a lawman who engenders deep bipartisan respect, was just getting underway.
CBS News said Thursday, "The laptop bomb that may evade airport scanners was built and tested by ISIS at Mosul University". He went on to say that Comey was widely "unpopular" and that he made the decision to fire the director on Deputy Attorney General Rod Rosenstein's recommendation.
"But he also felt that he could not refuse a presidential invitation, particularly not one that went to a broad array of law enforcement leadership. I look forward to this matter concluding quickly". "He can take care of himself", the Colombian president said.More news: Donald Trump says he fired James Comey because he was 'unpopular'
But he expressed more resentment Thursday in his tweets. He gave no examples.
But a report in the New York Times this week that Trump allegedly asked Comey to end the investigation undercut the president's rationale and has led to accusations from some in Congress that Trump was attempting to obstruct justice.
Mueller, a former federal prosecutor at the Justice Department, was confirmed as FBI director days before the September 11, 2001, attacks that would ultimately shape his tenure.
Some doubt whether Trump, a businessman-turned politician who never held elective office before becoming president in January, is ready for a smooth presidential debut overseas.
Rosenstein said the Mueller appointment was "necessary in order for the American people to have full confidence in the outcome".
But GOP lawmakers have grown increasingly anxious since Trump fired Comey, who had been leading the bureau's probe - and after Comey associates said he had notes from a meeting in which Trump asked him to shut down the investigation into Flynn's Russian Federation ties.
Other presidents have hired personal lawyers suited to an investigation by a special counsel or special prosecutor in the past. "You can't let them get you down, can't let the critics and the naysayers get in the way of your dreams".
