Why won't Trump lower the White House flag to half mast in honor of the officer who was killed by the mob?

Because he doesn't care.

It was his 'low class' supporters who killed that cop 'not me', just ask him.

Cuz he considers him a “loser.”

Three days after, he did. Not much for paying attention, are you?

Because what he said just before the riot was, in his words, "TOTALLY appropriate." A psychiatrist has said that people like Trump don't get depressed when they fail, just more delusional. The Republicans in Congress stand staunchly behind him.

Trump doesn't do that himself, you know.
