Keith Olbermann has found proof that President Trump is a terrible father. He simply added the number of Father’s Day tweets his adult children posted about him.

What a genius! Except that Olbermann’s tweet is pretty much all factually wrong. First, Trump has four adult children. Second, here are two tweets, one from Donald Jr. and another Ivanka. While math is hard, Olbermann should be able to see that two is greater than “1-1/2.” And third, he put the apostrophe in Father’s Day in the wrong place.

As for the other two children, Tiffany Trump seldom tweets, and Eric Trump sent this earlier.

Needless to say, it’s a far cry from a shot at his father. Olbermann has had a lot of dumb takes, but this one might be the champ.
