The president of the conservative watchdog group Judicial Watch thinks President Trump should shut down special counsel Robert Mueller’s investigation after former national security adviser Michael Flynn’s guilty plea.

“Sally Yates, Andrew McCabe, and James Comey improperly targeted General Flynn. And Mueller got him. Deep State victory. [Donald Trump] should consider a pardon,” Fitton tweeted Friday. “The Mueller special counsel continues to be unconstitutional and out of control. Shut it down.”

Flynn pleaded guilty to lying to the Federal Bureau of Investigation regarding his phone calls with the Russian ambassador to the U.S. Flynn is now the fourth former Trump campaign official to have faced charges due to the special counsel’s probe into alleged Russian election interference.

Trump could dismiss Mueller, which the White House says he has no intention of doing. Longtime Trump political adviser Roger Stone told The Daily Caller that Trump doesn’t need to fire Mueller soon after charges emerged against former campaign manager Paul Manafort.

He said that Trump should request the Justice Department appoint a new special counsel to look into an Obama-era uranium deal.

Mueller was the FBI Director when the sale of a Canadian firm that controlled around 20 percent of America’s uranium supply was sold to a Russian firm. “Mueller can’t be a special prosecutor when he himself is under investigation,” Stone said.

The Trump confidant added that Mueller intends “to levy phony charges against Trump in order to impeach him.”
