President Donald Trump speaks during a news conference with Colombian President Juan Manuel Santos in the East Room of the White House in Washington, Thursday, May 18, 2017.
The FBI is investigating alleged Russian meddling in the 2016 election, including looking into any possible links between Trump campaign associates and the Kremlin.
The appointment follows bipartisan calls for a more independent investigation into President Donald Trump's potential ties to Russian Federation. "I hope that former Director Comey's testimony will help answer some of the questions that have arisen since Director Comey was so suddenly dismissed by the president", the top Democrat on the Senate Intelligence Committee, Mark Warner, said in a statement yesterday.
Comey will certainly be asked about encounters that precipitated his firing, including a January dinner in which, Comey has told associates, Trump asked for his loyalty.
The new headlines were a fresh indication that Mr Trump would not be able to change the subject from what appears to be an intensifying investigation reaching toward the president and his inner circle.
In a statement released by the White House, Trump said: "As I have stated many times, a thorough investigation will confirm what we already know - there was no collusion between my campaign and any foreign entity".
Trump fired Comey last week.
"I just fired the head of the F.B.I. He was insane, a real nut job", the Times reported that Trump said during the May 10 meeting.
"I think it's good across the board", Luskin told Reuters. "By grandstanding and politicizing the investigation into Russia's actions, James Comey created unnecessary pressure on our ability to engage and negotiate with Russian Federation".
That flies in the face of the White House's public insistence that Comey's dismissal was not linked to his ongoing investigation. "The real story is that our national security has been undermined by the leaking of private and highly classified conversations".
Citing two unidentified sources, CNN reported that White House lawyers have begun researching impeachment procedures in an effort to prepare for what officials still believe is a distant possibility that Trump could have to fend off attempts to remove him from office.
In March, for example, the White House disclosed that Trump's son-in-law and White House senior adviser, Jared Kushner, met executives of Russian state development bank Vnesheconombank, or VEB, in December.
Republican Representative Jason Chaffetz, the chairman of the House Oversight and Government Reform Committee, requested the documents be delivered by May 24 and said he would subpoena the information if necessary.
President Donald Trump on Thursday denied ever asking FBI Director James Comey to back off his agency's investigation into possible collusion between the Trump campaign and Russian Federation, and the role played by former national security adviser Michael Flynn.
He says his memo is not a finding of official misconduct and is not a statement of reasons to justify Comey's firing.
Wittes, who is a friend of Comey and an outspoken critic of President Donald Trump, says that the then-FBI director expressed overt reservations about then-unconfirmed Rosenstein during a relatively casual lunch.
"Rod is a survivor", Comey said, according to Wittes' personal post on the Lawfare blog.
Press Secretary Sean Spicer said Friday that no announcement is imminent.
Trump told them the appointment would allow them to refer questions to Mueller, giving them space to focus on policies such as tax reform.
Rep. Dave Trott (R-MI) told the Associated Press that at one point in the closed-door meeting, Oversight Committee ranking member Rep. Elijah Cummings (D-MD) got up and asked: "So you just woke up one morning and made a decision to write a memo?" "I don't think (Rosenstein) did a lot to bolster our confidence in him today".
