I say “was” because this video from some years ago contains a goodly amount of “trutherism”. Trump raises some very responsible doubts about the official story of what happened on 9/11. This is when it didn’t cost him anything politically.
But when he wanted our votes, and he knew like any skilled politician that he could gain massive support by playing to people’s fears, he claimed that he saw thousands of Muslims dancing in the streets celebrating the attacks.
As he likes to end his tweets, sad.
