CORNISH: Now, if the president is so down on Mueller, why not fire him? Rosenstein said he has seen no evidence of good cause to fire the special prosecutor overseeing the Russian Federation investigation.
"First, most simply, Trump could order Mueller fired", Katyal said.
He did not explicitly endorse Sessions' appearance, saying in response to a question, "We're aware of it, and we'll go from there". The regulations governing independent investigations make clear that the special counsel can be removed "only by the personal action of the Attorney General". The political implications of firing Mueller would be meteoric, and perhaps too self-destructive even for Trump.
It took about 24 hours, but the White House has knocked down speculation that President Donald Trump considered firing special prosecutor Robert Mueller. "If there were not good cause, it would not matter to me what anybody said", he said.
He added, "I'm not going to follow any order unless I believe those are lawful and appropriate orders".
The Washington Post reported Tuesday that the interviews represent a widening of the probe to include a query into whether the President obstructed justice in suggesting to his former FBI Director James Comey that he drop the investigation into Michael Flynn, Trump's former national security adviser, as well as for firing of Comey.
A senior White House official confirmed that the president had interviewed Mueller for the FBI post in the Oval Office the day before Rosenstein tapped him to be the special counsel in the Russian Federation investigation.
As Mueller builds his legal team, Trump's allies have begun raising questions about the former Federal Bureau of Investigation director's impartiality, suggesting he can not be trusted to lead the probe.
Politico's Josh Dawsey tweeted, "White House officials are trying to tamp down Chris Ruddy's TV comments about Trump possibly firing Mueller". He is nearly certain to be asked about the possibility of the president firing Mueller.
"I think it is a consideration the President has had, because (Robert) Mueller is illegitimate as special counsel", Ruddy told CNN's Chris Cuomo on "New Day" Tuesday. "I think it is", Ruddy said.
"Republicans are delusional if they think the special counsel is going to be fair".
Less than a month ago, he called Mueller a "superb choice", someone whose "reputation is impeccable for honesty and integrity". Trump was especially outraged by Comey's admission last week that he had leaked a memo with details of his interactions with the president in hopes of spurring the appointment of a special counsel.
"T$3 his is beyond now ridiculous and another reason why this special counsel Mueller needs to be shut down immediately, on top of the fact we know there's no collusion", Hannity added.
"The attorney general is the one who has to fire him", said CNN's senior legal analyst Jeffrey Toobin on "Anderson Cooper 360". The person spoke on condition of anonymity to discuss private conversations.
High-profile supporters of Donald Trump have begun attacking the independent investigator looking into the Russian Federation affair, raising the question of whether the president could indeed attempt to fire him.
"Look, the president of the United States, as we all know, is a unitary executive", Jay Sekulow said on ABC's "This Week."
