MATTHEW WALTHER: The humorless media has learned nothing.

President Trump sent many journalists into hysterics on Wednesday when he tweeted that he might “take away” press credentials from unspecified purveyors of “Fake News.” “Why do we work so hard in working with the media when it is corrupt?” the 71-year-old real-estate tycoon tweeted at 7:38 a.m., presumably in his pajamas. “Take away credentials?” The press met this obviously inane and idle threat not with an eye roll, but with gasps and whinges and cries of alarm. It was an “assault on the First Amendment,” the White House Correspondents Association huffed.

Spare me. Here is the painful truth for the emotional kindergartners who increasingly make up the Washington press corps: Our 45th president was making a joke to rile you up because he thinks it’s hilarious.

Whether or not you found the President’s tweet humorous, the press’s reaction to it has been hysterical.
