President Donald Trump took up his media Twitter cudgel again Saturday night and went after “Little Donny Deutsch” after the MSNBC host called him a criminal.

Trump called Deutsch “a total loser” in a tweet, then just minutes later said in another post: “I know it it is not at all ‘Presidential’ to hit back at the Corrupt Media.”

Deutsch has been particularly hard on Trump lately. On Friday he called him a “despicable human being” on “Morning Joe” for attacking House Speaker Nancy Pelosi (D-Calif.) as Trump was interviewed in front of the gravestones of war dead in France on the anniversary of the D-Day landings.

Deutsch also suggested more than a week ago that “impeachment” should be “rebranded” as the “Trump criminal investigations.” That foreshadowed Pelosi’s reported comments that she’d rather see Trump in prison than impeached, which infuriated the president. “He’s a criminal,” Deutsch said flatly.

Deutsch took up that rebranding campaign again on his program “Saturday Night Politics,” which was likely what wound Trump up.

But instead of attacking the host’s comments, Trump went after Deutsch’s claims that the men were once friends.

“This is false ... hardly knew him — other than to know” he’s a “total loser,” Trump tweeted. The president claimed that Deutsch and CNN’s Erin Burnett had “begged” him to be on his TV show “The Apprentice,” but he turned them down.
