Actor Alec Baldwin is not amused by former House Speaker Newt Gingrich's shifting opinion of special counsel Robert Mueller and wants him to "shut the fuck up."

Throughout the week Gingrich has raised concerns over the impartiality of Mueller, a former FBI director, who is leading the federal investigation into Russian meddling in the 2016 election. In a series of tweets Thursday of being tip of the 'deep state spear' trying to bring down Trump. Then on Friday he quipped on Fox News that a special counsel needs to look into the special counsel.

After Gingrich's appearance on "Hannity," which was promoted by the president, Baldwin shared a May 17 tweet from Gingrich praising Mueller. "Robert Mueller is superb choice to be special counsel. His reputation is impeccable for honesty and integrity. Media should now calm down," the tweet reads.

"Newt should shut the fuck up," Baldwin said in response.

Baldwin, who portrayed Trump in the latest season of Saturday Night Live in a not-so-flattering way, has been a constant critic of the president.
