The FBI is investigating the Russians' involvement.
Democrats have pushed for a special prosecutor nearly universally, saying Trump fired Comey to short-circuit the investigation into possible ties between the Trump campaign and Russian operatives.
Trump predicts quick nomination to replace Comey at FBIU.S. President Donald Trump is predicting a quick nomination process to replace the Federal Bureau of Investigation director he fired this past week.
In the initial moments after Comey's firing, Trump's press secretary, deputy press secretary and Vice President Mike Pence all said Trump's decision was based on the recommendation of Deputy Attorney General Rod Rosenstein.
The BBC's Laura Bicker in Washington says Mr Trump was referring to a private White House dinner in January during which the president claims Mr Comey assured him he was not being investigated over alleged links to Russian Federation.
He explained that Trump was "dismayed" that at press briefings, "we see time and time again" how the media is trying to "parse every word".
During a Friday morning tweetstorm, the president appeared to imply that there are tapes of his private conversations with Comey, who Trump fired earlier this week. "Maybe the best thing to do would be to cancel all future "press briefings" and hand out written responses for the sake of accuracy???" "The president has nothing further to add on that", Spicer said as he repeated the same answer every time he was asked on this issue.
A few hours later in the White House briefing room, as dark clouds comically formed outside, reporters naturally had some questions.
If he wasn't taping conversations in the White House, it would be easy for Trump to say so. Later, the president and his advisers said Mr Trump had planned to fire Mr Comey since taking office.
Donald Trump warned ousted FBI Director James Comey on Friday not to talk to the media. "I'm moving on", Spicer said. "I think it's a good idea", Trump said. In the NBC interview on Thursday, Trump said he would have fired Comey regardless of any such recommendations.
When questioned about the statement that the director informed the president he wasn't the subject of an FBI investigation, Trump told Holt that Comey informed him over dinner.
Democrats cast the decision to fire Comey as an effort to obstruct the FBI's probe, a charge the White House has denied.
