Given that the attorney general, Jeff Sessions, has already recused himself from any investigations into Russia's involvement in the 2016 election, the official who would be placed in charge of appointing such a special prosecutor would be Rosenstein.
Sen. Lindsey Graham of SC on CNN's "New Day": "I think Director Comey is a fine man, but Democrats called for his removal about two to three, four weeks ago and now he's gone and we get a chance to pick on a new director that hopefully we can all agree is above reproach".
Sarah Huckabee Sanders said over the last several months Trump had "lost confidence in director Comey, the Department of Justice lost confidence in director Comey, bi-partisan members of Congress made it clear they had lost confidence in director Comey and most importantly the rank and file of the Federal Bureau of Investigation had lost confidence in their director".
Sen. Amy Klobuchar even asked Comey about Deputy Attorney General Rod Rosenstein, who wrote the memo President Trump used as the basis for firing Comey.
Ousted FBI Director James Comey
The White House also issued a timeline claiming how Trump lost confidence in Comey over the course of the last several months.
The speaker called on the White House to nominate a "capable" replacement for Comey "very soon" and sought to reassure the FBI's rank-and-file that "their jobs are valuable and that they have to keep doing what they're doing [and] do their jobs objectively and thoroughly".
In defending the decision, officials leaned on a memo from Mr Rosenstein, the deputy attorney general, that criticised Mr Comey's handling of the Clinton investigation.
The Justice Department denied that Comey had asked for more resources for the investigation.

Congress by saying it supported United Nations Security Council resolutions but opposed the imposition of "unilateral sanctions". The North Korean statement said the plan had "been put into the extremely serious phase of implementation".
Democrats renew calls for appointment of a special prosecutor to investigate Kremlin links. In public hearings, Comey has declined to answer when asked if Trump is under investigation, urging lawmakers not to read anything into that statement.While Comey has drawn anger from Democrats since he reopened the email investigation in the closing days of last year's campaign, they didn't buy that justification for his firing.
Earlier in the day, Kremlin spokesman Dmitry Peskov said Trump's decision was an "independent decision, which has nothing to do and should have nothing to do with Russian Federation".
That acknowledgement, The Times said, set Trump off: "Mr. Trump burned as he watched, convinced that Mr. Comey was grandstanding". The Washington Post reports he was so upset that Trump made him out to be the prime culprit in the decision to fire Comey that he threatened to resign!
Trump said in an April 12 interview on Fox Business News that he had confidence in Comey, but left the door open for his opinion to change.
Trump may meet top Russian diplomat in White House
Trump has said he has no ties to Russia and isn't aware of any involvement by his aides in any Russian election interference. Still, the overlap between the investigation and Trump's diplomatic efforts made for uncomfortable optics.
"To a president obsessed with loyalty, Mr. Comey was a rogue operator who could not be trusted as the FBI investigated Russian ties to Mr. Trump's campaign", The Times reported. Some have then wondered aloud if the president is instead trying to punish Comey for investigating ties between his campaign and Russian Federation. The Comey firing throws the future of the Russian Federation probe into doubt, but it's not going away.
Who is brought in now to lead the FBI will be a key indicator of how investigations into sensitive areas like the probe into Russian meddling in the U.S. election will proceed, the first official said.
Andrew Arena, a former special agent in charge, said current FBI employees he spoke with as news of Comey's ouster spread anxious about the future of the bureau. "They didn't just happen this morning".
In his dismissal letter to Comey on Tuesday night, Trump claimed that Comey informed him, "on three separate occassions", that he was not under investigation, but according to Comey associates cited by The Wall Street Journal, that assertion was inaccurate.
