White House officials, however, have rejected such comparisons, and, echoing their boss, say the FBI's investigation into Russia's election meddling and possible nefarious ties to his campaign is a minor matter on the bureau's docket. His assertions came as Comey's temporary replacement joined in, contradicting other administration statements on the snowballing controversy.
The White House said Trump asked his lawyers for the letter following a request from Sen.
Critics have assailed Trump for dismissing the Federal Bureau of Investigation chief just as the agency is investigating alleged Russian meddling in the 2016 USA election, and possible Moscow ties to the Trump presidential campaign.
"I think the process is going to go quickly", he said, adding that the candidates under consideration were mostly well known.
Acting FBI Director Andrew McCabe is among the dozen candidates U.S. President Donald Trump is considering to succeed ousted FBI Director James Comey.
The Trump administration is looking to fill the job, which requires Senate confirmation, after Mr Trump abruptly fired director James Comey last week.
After four months in office, President Donald Trump has become distrustful of some of his White House staff, heavily reliant on a handful of family members and longtime aides, and furious that the White House's attempts to quell the firestorm over the FBI and congressional Russian Federation investigations only seem to add more fuel.
Trump says Comey had told him three times he was not under investigation in the Russian Federation probe.
Trump will encourage students to "be a force for good in the world by standing up for the values that Liberty has taught them", White House spokesman Sean Spicer said. Not even Vice-President Mike Pence was spared the embarrassment of having told a version of events that was later discredited by Trump.

He has taken a more conciliatory line with North Korea than his conservative predecessors and advocates engagement. They agreed the bilateral relationship would continue to go from strength to strength.
"That is not accurate", McCabe said.
"I have long believed that a President can fire an FBI Director for any reason, or for no reason at all", he wrote.
Before Mr Comey tapped him to lead the Richmond office in 2014, he was chief of the Public Corruption and Civil Rights Section, investigating some of the highest profile cases against government officials and civil rights violations in recent years. McCabe told a Senate panel it was not "standard practice" to tell an individual whether they are or are not under investigation.
Mr. President, if there are "tapes" relevant to the Comey firing, it's because you made them and they should be provided to Congress. Trump's comments demonstrated his striking deviation from that practice.
An enraged President Trump escalated feuds with his critics, detractors, and even dissed his own aides on a furious Friday as Washington descended into internecine warfare and political bloodletting over alleged Russian involvement in USA politics. If the trouble were Mr Comey's handling of Mrs Clinton's e-mails, he could have been sacked four months ago.
He continued, "I actually asked him, yes". But just days later, Trump criticized Comey for "protecting" Clinton, despite the FBI's conclusion that criminal charges were unwarranted.following the election, President Trump called Comey "more famous than me".
Comey had wisely briefed members of Congress in the past week, telling them of his request to Rod Rosenstein, the deputy attorney general, for more agents to conduct a much broader investigation.
But it quickly became clear that the president had been stewing for days over the Russian Federation investigation and Comey's refusal to defend him in appearances before lawmakers.
Mr Trump said it was "possible" he could name someone by Friday, before he leaves for his first foreign trip.
