Sessions and President Trump have had a contentious relationship nearly from the start of the administration, and the attorney general's reluctance to crack down on legal cannabis states could theoretically be attributed, in part, to that dynamic. And did his campaign have advance knowledge of illegally hacked Democratic emails?
Earlier on Wednesday, Mr Trump denied he would shut down Mr Mueller's team, but still labelled the investigation an illegal "witch hunt" that had spent "millions" of dollars.
On Wednesday, Goodlatte issued a statement praising Sessions' service as attorney general and wishing Whitaker well in his new role.
Mitt Romney, the Republican Party's 2012 presidential nominee who won the Utah race on Tuesday to become a USA senator, also said Mueller's probe should not be affected by Sessions' dismissal.
That drew criticism from Democrats because Whitaker, who would now take over responsibility for overseeing Mueller and his investigation, has been critical of the Mueller probe, saying it should be scaled back.
Phil Sawyer said he's been concerned about Trump's politics for some time. But the work is not done. He has previously suggested drastically reducing the budget of Mueller's special counsel probe, in order to thwart Mueller's threat to the president's constitutional mandate.

At a protest in support of Mueller outside the White House, a crowd of several hundred protesters shouted anti-Trump slogans.

The counselor to the president went on to give credit to Sessions for his work at the Department of Justice, including cracking down on opioid abuse as well as the MS-13 gang.
"Trump's actions are being compared with those of U.S. President Richard Nixon in one of the most controversial episodes of the Watergate scandal, the Saturday Night Massacre", said organizers. Federal prosecutors have said in court papers that the case involves numerous "uncharged" third parties and have argued against disclosing search warrants and other documents that would "certainly result in a very public guessing game" about their identities. Whitaker did, however, believe that Sessions had no choice but to recuse himself from the matter, the person said. In the months before, Whitaker was a familiar presence on CNN, where he questioned Mueller's scope and reach. Stone's visits to Trump Tower in NY before the 2016 election.
Asked whether Whitaker would assume control over Mueller's investigation, Justice Department spokeswoman Sarah Flores said Whitaker would be "in charge of all matters under the purview of the Department of Justice". Schumer and Democrat Nancy Pelosi, who is likely to become House speaker next year, called on Whitaker to recuse himself, with Schumer citing "his previous comments advocating defunding and imposing limitations on the Mueller investigation".
