Is there nothing too petty for this president?

Early Thursday morning, President Donald Trump took to Twitter (where his current follower count is 67.5 million) to attack a 16-year-old girl with Asperger’s syndrome and tell her to “work on her Anger Management problem.”

As always with Trump, when he accuses someone else of something, we get a window into what he himself is feeling. So it’s fair to ask: What did Swedish climate activist Greta Thunberg do to make the projectionist-in-chief so hopping mad?

The answer: She was named Time magazine’s Person of the Year.

Time covers are something of a fixation for this president. Back when he was a reality-TV star, he decorated the walls of at least five of his golf clubs with fake ones featuring his own face.
