Trump's latest tweet alluding to the possibility of recordings further added to the heightened drama of the past two days as the White House tries to do damage control on the messaging surrounding Comey's firing. A strong chief of staff or White House Counsel's Office would have insisted on a well-prepared and carefully defended process to remove the FBI director if that were necessary - and would have counseled against doing it at all while the director was ramping up an investigation of Trump's campaign. "I$3 t is a crime to intimidate or threaten any potential witness with the intent to influence, delay, or prevent their official testimony", they say in the letter. "It could be very problematic", said Michael German, a former Federal Bureau of Investigation special agent.
Trump's administration - embroiled in a deepening crisis over the sacking and its shifting explanation of events - is interviewing the first candidates for the post on Saturday, US media reported. That has led to speculation that Trump is considering replacing him.
They said that they are also requesting "all documents, memoranda, analyses, emails, and other communications relating to the President's decision to dismiss Director Comey" and asked that McGahn respond to them by May 25.
Trump had also asked for a preview of senate testimony that Comey was to give on the Clinton email and Russian Federation investigations, and Comey refused that, too.
United States President Donald Trump called on graduating seniors to resist the urge to quit and to ignore their critics as he delivered the commencement address at Liberty University, the nation's largest Christian college, on Saturday.
Reaction to President Donald Trump's decision to fire FBI Director James Comey tilts negative, an NBC/Wall Street Journal poll released Sunday has found.
The House earlier this month passed the American Health Care Act, which Trump has said he supports.
Trump also hit back on Friday at media reports questioning the credibility of White House accounts of why Comey was sacked, which have changed over the course of the week, and threatened an end to regular White House press briefings.
"It's improper", a former high-level Justice Department official said.More news: Trump willing to try engagement with North Korea, on conditions: Seoul
Those Democrats, Reps. Elijah Cummings of Maryland and John Conyers of MI, also requested "all documents, memoranda, analyses, emails, and other communications relating to the President's decision to dismiss Director Comey - a decision which the president declared yesterday he planned to make "regardless of [Deputy Attorney General Rod Rosenstein's] recommendation" - and all discussions with Director Comey".
The two senior congressmen wrote that "under normal circumstances, we would not consider credible any claims that the White House may have taped conversations of meetings with the president".
The poll found 23 percent believe the bill is a "good idea", 48 percent say it is a "bad idea" and 28 percent have no opinion.
At home in Russia, Kremlin-controlled media have also been having a field day, with cartoons ridiculing the political farce in Washington. Trump said Comey wanted to have the dinner because he wanted to stay on in the job.
In a statement, Durbin said that what he characterised as Trump's admission that he fired Comey because of the Russian Federation probe was "dangerously close to obstruction of justice".
Democrats criticized Trump's comments with some requesting a copy of the recordings.
Reportedly, Trump had sought assurances of loyalty from Comey, which Comey rightly refused to give.
Trump, on Friday, appeared to suggest on Twitter that if Comey presented his version of contact between him and the Republican president, then the administration may produce tapes of conversations of them.
Others under consideration include Michael Luttig, executive vice president of Boeing and a former federal appellate court judge; Michael Garcia, a NY state Court of Appeals associate judge; John Suthers, mayor of Colorado Springs, Colo., Paul Abbate, an FBI executive assistant director; and McCabe, the acting director, the official said.
