Sessions, a 71-year-old former Republican senator from Alabama, was the first senator to endorse Trump's insurgent presidential campaign.
Nadler is expected to become House Judiciary chairman when a Democratic House majority, elected in Tuesday's midterm elections, takes over in the new Congress that convenes in January. Sessions recused himself in March 2017 because of his work on Trump's campaign and following the revelation that he had met during the 2016 campaign with the Russian ambassador to the U.S.
Only minutes later, a series of questions he found overly hostile sent him into a most un-loving blowup.
The announcement has prompted major questions about the future of the Russian Federation investigation and whether Trump will target Mueller next.
He found satisfaction in being able to reverse Obama-era policies that conservatives say flouted the will of Congress, encouraging prosecutors to pursue the most serious charges they could and promoting more aggressive enforcement of federal marijuana law.
The row, carried live on national TV networks, was followed by Trump issuing angry put-downs to several other reporters. The undated letter was then sent to the White House.
The midterms show Trump might not get re-elected in 2020
The GOP's successes were fueled by a coalition that's decidedly older, whiter, more male and less likely to have college degrees. And it doesn't even mean they weren't really important issues for many - even most - of those who voted for Trump.
New York City Rep. Jerrold Nadler - who is now the ranking Democratic member of the House Judiciary Committee and could be the next chairman of the committee with Democrats taking control of the U.S. House of Representatives - questioned the president's move on Twitter and said that "we will be holding people accountable".
"We're a co-equal branch in the government, and we have a responsibility to understand what happened in 2016 and to prevent it from ever happening again", King said.
Des Moines attorney Guy Cook, a Democrat who has known Whitaker for years, called him a clear thinker and a "no-nonsense guy who is not to be underestimated".
Mueller's probe has since reached plea deals with or indicted a number of Trump associates.
"It was supposed to be on collusion".
"I'd like them to protect the Mueller investigation. Had nothing to do with my campaign".
Midterms 2018: Firsts for women in the US House
Others made a decision to skip the subtlety, blatantly accusing women who cast votes for Republicans of white supremacy. Many female Democratic House candidates who prevailed on Election Day ran in opposition to Trump or his policies.
Trump said at the news conference that he wanted the Mueller probe to end, calling it "very unfair".
The appointment generated immediate controversy given Whitaker's previous public comments criticizing the probe. Trump has not interfered with it yet, despite repeatedly labelling it a "hoax" and a "witch-hunt".
According to legal analysts cited by The Guardian, Trump's decision may set off a constitutional crisis over the fate of the Mueller inquiry, which followed a conclusion by United States intelligence agencies that Russian Federation intervened to help Trump win in 2016.
It is not obstruction of justice if the president does it. "No one is above the law", Schiff said.
One of the exceptions, Senator Susan Collins, said non-interference in the Mueller probe was "imperative".
