The White House also shifted its stance on whether Comey's termination had anything to do with the Russian Federation investigation, at first saying it was not linked.
Mr Trump's fascination with recording his conversations goes back to the early years of his real estate career, when he installed in his 26th-storey office in Trump Tower a "system for surreptitiously tape-recording business meetings", according to an eyewitness account in journalist Harry Hurt's 1993 biography, Lost Tycoon.
Republicans privately express concern that the White House is careening out of control and are becoming more critical in public too. He's held a number of other positions with the agency. Speaking in Boston, Comey was confident he would serve his full 10-year term.
Comey confirms that the FBI is investigating alleged ties between Trump's election campaign team and the Russian government. She faced resistance from Democrats during her confirmation over her alleged participation in discussions about detention policies at the Guantanamo Bay facility in Cuba.
Russian Federation denies the claims and the White House says there was no collusion.
Among those expected to be coming in Saturday are acting Federal Bureau of Investigation director Andrew McCabe and Alice Fisher, a top Justice Department official in the George W. Bush administration.
The U.S. Senate's No. 2 Democrat, Richard Durbin, slammed the president after Friday's tweet about Comey.
"White House briefings and press conferences provide substantive and symbolic opportunities for journalists to pose questions to officials at the highest levels of the USA government".
"You don't want to do that because it shows you as weak", Dallek said.
Trump says "even that is possible". Lawyers tend to look into every potential pitfall and problem.
Many Republicans are eying the 2018 midterm elections, which will put control of the House of Representatives and potentially the Senate up for grabs. "I'm sure he is discovering that and it's proven to be a bit surprising or a source of frustration".
The president stressed that Comey had told him each time that he was not targeted in the investigation; however, the remarks quickly raised allegations of presidential interference in the investigation.
The president said the change, if implemented, could happen "over the next couple of weeks".
"Did you ask him to drop the investigation?" "He's a very patriotic American".
"I'll tell you what, they'll be very unhappy", Trump said of news networks, "because the ratings are so high that I don't know what these networks are going to do".
"There was never any sense with Donald of the phone being used for private conversation", said John O'Donnell, who was president of the Trump Plaza Hotel & Casino in the 1980s.
When asked about the tweet, press secretary Sean Spicer refused to talk about it.
Proven allegiance to Trump is among the most valuable currencies within the administration.
According to Quinnipiac's Tim Malloy, Trump is losing ground with white men, white voters without college degrees and independent voters. Ms. Yates's testimony focused public attention on the office of White House counsel, given that it took 18 days and a public leak to remove the Russian "compromised" Mr. Flynn. He later said he was "not aware" whether any White House official had recordings of the conversation and wouldn't comment on whether the president regularly recorded conversations in the Oval Office.
Two new names, however, emerged on Saturday: FBI special agent Adam Lee and U.S. District Judge Henry Hudson.
