Donald Trump Jr. shares tweet calling Robert Mueller ‘mentally retarded’

While former Special Counsel Robert Mueller was testifying before the House Judiciary Committee on Wednesday, President Donald Trump’s son, Don Jr., was tweeting up a storm, with most of his posts and retweets attacking Mueller, a decorated Vietnam war veteran.

But one tweet was especially nasty. It was a comment Don Jr. made regarding a post from convicted felon and right-wing gadfly Dinesh D’Souza:

Much like his father, Junior is always willing to prove his own heartless disregard for others. He has no problem attacking someone he disagrees with merely for a cheap laugh.

But Don Jr. was immediately pelted with reminders that Mueller had also said his report didn’t exonerate the president:

Stay classy, Junior!
