If anyone was still in any doubt that President Trump was an embarrassment to his office, it should have been dispelled by the latest example of what Trump calls his “modern day presidential” use of social media.

I’m referring, of course, to his tweet featuring a doctored version of a video — apparently appropriated from Reddit — showing him attacking a man with the CNN logo superimposed on his head. The original 2007 video featured Trump body-slamming World Wrestling Entertainment CEO Vince McMahon. (The White House now says that the video tweeted by Trump didn’t come from Reddit.)
