From The President is a Psychopath:
We are psychologists, and we are convinced Donald Trump is a psychopath. His malignant behavior over the past four years is growing and escalating right before our eyes. Trump’s psychopathy will change us forever if he is not stopped. This is not hyperbole. This is not an expression of “a left-wing agenda.” This is a mental health opinion based on thousands of hours of documented behavior by this president.
