The president seemed to be responding to news stories coming out since the Tuesday firing, which have contradicted the White House's version of the events.
"We have got to make sure that these tapes, if they exist, don't mysteriously disappear", he said.
President Trump suggested on Twitter Friday morning there might be recordings of his private conversations with former FBI Director James Comey, whom he fired earlier this week, in an apparent attempt to caution Comey against "leaking to the press".
Officials tell the New York Times that the White House wants to pick a candidate without close ties to Trump to avoid accusations it he is trying to derail the Russian Federation probe.
Press secretary Sean Spicer is refuting that account during his daily briefing. He promised he would tolerate no interference from the White House and would not provide the administration with updates on its progress. "That was a DOJ decision".
Sources close to Deputy Attorney General Rod Rosenstein say he is not in favor of appointing a special prosecutor to investigate Russia's alleged involvement in the 2016 presidential election. According to Sanders, Trump then asked Rosenstein to give his recommendation in writing. "But they came to him on his own".
Spicer denied on Friday that Trump asked Comey to pledge his loyalty, insisting that the president simply "wants loyalty to this country and the rule of law". The White House denies the account.
"Oh, I was gonna fire regardless of recommendation", Trump told NBC's Lester Holt.
Spicer said Trump's tweet cautioning Comey about potential tapes of their conversations was "not a threat", either.
May 16, 2017: A person familiar with the situation tells The Associated Press that Comey wrote a memo after the February 14 meeting with the president that said Trump had asked him to shut down the FBI investigation into Flynn. "The president has nothing further to add on that", Spicer replied. In this atmosphere, it's better for spokespersons to signal they are out of the loop. Trump said the discussions happened in two phone calls and at a dinner in which Comey was asking to keep his job. "If the election were on October 27, I would have been your president", she tells a women's luncheon in NY. But in the future, Pence could see reason to backpedal his rhetoric in order to safeguard his reputation as a straight shooter.
Trump's statements, through a tweet and later television interview, threaten a Washington institution that is the most high-profile forum for journalists to question the government about policy and the news of the day.
Rosenstein's memo, on the other hand, hit Comey for being unfair to Clinton by speaking to the press in July and broadcasting the FBI's decision to reopen the investigation in October.
The 49-year-old McCabe, a career FBI agent, has taken part in a number of high-profile investigations, including probes into the Boston Marathon bombing in 2013 and the attacks against U.S. installations in Benghazi, Libya in 2012.
Sen. Mark Warner, the ranking Democrat on the intelligence panel, said Friday that he expressed at his meeting with Rosenstein and Boente his preference that Rosenstein name a special prosecutor.
