So many things wrong with it.
The funniest is the analogy to prosecution in court.
The judge would ask Trump if he is a Doctor with an expertise in psychology. His diagnosis would not be accepted by the court.
That’s funny.
The serious part is trying to smear Carson via his own Christian testimony.
The dumb part is thinking that adolescent stupidity would be telling in any way of Carson’s character.
As Trump points out, he’s quoting Carson in Carson’s own book. Carson calls it pathological in his book. Trump is simply repeating what Carson wrote.
