answer:Donald Trump exhibits maladaptive behavior meant to buttress his warped worldview. He quite possibly has a mental disorder that is undiagnosed. It is inappropriate to state what that diagnosis may be outside a clinical setting. What we are witnessing now are the outrageous lengths individuals will go to in order to maintain their own internal fiction. It must be noted that this behavior is not limited to Trump. His supporters are doing it, too. Faced with facts, they cling to their fictions. The pain of releasing their fictions appears greater than the pain of accepting truth to both Trump and his supporters.
