Robert Mueller's Russian Federation investigation and other topics were drawing scrutiny from Democrats and ethics groups.
"He's a fucking fool", one attorney told reporter Erin Banco of the new appointee, who served as chief of staff for the previous attorney general, Jeff Sessions "He's spent so much time trying to suck up to the president to get here".
Protests around the country, including Orlando, were organized Thursday in response to President Donald Trump's decision to name Matt Whitaker as acting attorney general.
Even after he arrived at the Justice Department, Whitaker harbored frustration about the length of the special counsel probe and doubts about the scope of Mueller's authority, a person familiar with the matter said.
Before departing for Paris on Friday, President Donald Trump made a point of insisting he wasn't familiar with newly appointed acting Attorney General Matt Whitaker.
Graham at the time said: "Any effort to go after Mueller could be the beginning of the end of the Trump presidency".
Whitaker is expected to oversee Mueller's investigation into potential coordination between Trump's 2016 Republican campaign and Russian Federation.
He said none of those apply in this case, as Whitaker is not deputy attorney general, he did not receive Senate confirmation for his current role at the DOJ and the Senate is not in recess.
Sessions' firing immediately threw into question whether the 18 month old Mueller probe will be able to continue unimpeded.
Whitaker has no intention of recusing himself from overseeing the Mueller probe, the Washington Post reported.
Trump then tried to take a shot against Mueller for not being "Senate confirmed" - while also claiming that Whitaker, the former United States attorney for Iowa, has been.
Despite Whitaker's appearance at several White House meetings, Trump said he does not know him very well but that he is "very, very highly thought of". Look for Whitaker to reduce Mueller's operating budget, pull lawyers and investigators now working on Mueller's team back to DOJ, refuse to authorize grand jury subpoenas or indictments, and/or push Mueller to wrap up the probe as soon as possible. "And the people have to speak out as you're doing today". In many instances, that office does not require a Justice Department official to recuse, but suggests a course of action.
As for the reports on Trump, if Whitaker suppresses them, the House Judiciary Committee could subpoena them and make them public.
