However, for most of Trump's critics who have been anxious about his presidency since the day after the election, seeing a President Pence would likely be cold comfort.
The appointment of a special counsel to investigate possible collusion between his campaign and Russian Federation was the "single greatest witch hunt in American history", he tweeted.
Mr Comey was ousted just days after he testified on Capitol Hill about the FBI's investigation into Russia's election meddling and possible connections between Russian Federation and Mr Trump's campaign.
But even before Comey's possible "paper trail" documenting President Trump's demands (which may or may not actually rise to the level of impeachable offense) came to light, his enemies were out in force.
But a report in the New York Times this week that Trump allegedly asked Comey to end the investigation undercut the president's rationale and has led to accusations from some in Congress that Trump was attempting to obstruct justice.
The White House vigorously denied it all.
Trump's legislative agenda is in danger, and reports circulated Thursday that the president was being advised to find outside counsel.
House Oversight Committee Chairman Jason Chaffetz has scheduled a full committee hearing on the FBI's independence for May 24.
President Donald Trump's White House has been plunged into crisis mode - once again - by explosive claims that he tried to quash an FBI investigation, and divulged secrets to top Russian officials.
Trump fired Comey as head of the FBI last week, saying the dismissal was driven by a loss of faith in the bureau chief on behalf of both himself and the public. "The FBI has not had that special reputation with what happened in the campaign, what happened with respect to the Clinton campaign, and even you could say directly or indirectly with respect to the much more successful Trump campaign", he said.
The White House will not say whether Trump recorded conversations in the Oval Office.
Does this rise to the level of criminal obstruction of justice?
"He didn't think there wouldn't be any charges brought - a statement that I think was regarded in some quarters as the king's wish", Mukasey said.
Another famous example of top-down politicization comes from President Richard Nixon, who obstructed the special investigation in the Watergate scandal. "But that's not anyone's place to speculate, the alleged memo has not been released". The people who "rock the domestic political situation in the US" under the guise of anti-Russian slogans are "either stupid or risky", the Russian president said. Loudermilk said Wednesday that after spending an 11-day recess back home, he's convinced his voters remain strongly supportive of the president.
Many in the steady stream of headlines about the Russian Federation investigation have been generated by Trump himself, making it more challenging for his administration to refocus on policy issues.
Speaking of the MS-13 gang presence in the US: "A terrible, frightful large group of gangs that have been let into our country over a fairly short period of time". "There's a whole litany of boxes that have to be checked, and a memo's just not going to reach that standard".
WASHINGTON (AP) - Surrounded by multiplying questions, President Donald Trump complained Wednesday...
"Donald Trump should start every morning with a tweet about what he is doing that day to help working-class Americans", said Republican strategist Alex Conant. Bill Cassidy and U.S. Rep. Clay Higgins, R-Port Barre; and U.S. Rep. Mike Johnson, R-Bossier, did not grant interviews.
Trump, whose administration has been dogged by allegations that Russia helped him win the White House and that he and his allies are too cozy with Moscow, has defended his decision to discuss intelligence with the Russians after media reports of the meeting alarmed some USA and foreign politicians.
