In short Donald Trump lies compulsively in large part because of who and what he is - a coward. This is why Mike Brzezinski said recently, "He brings nothing to the table.

Donald Trump is a liar because he is a coward. It is fear and cowardice that make him lie. it is his fragile ego that makes him lie.

Donald Trump has been called, by psychologists and clinical psychologists, over and over again, a narcissist with multiple sociopathic and psychopathic tendencies.

Lying is second nature to him... More than anyone else I have ever met, Trump has the ability to convince himself that whatever he is saying at any given moment is true, or sort of true, or at least ought to be true.

Lies are like cockroaches, for every one you discover there are many more that are hidden.

Why not look instead for evidence of cowardice, secrecy, and dishonesty -- the traits displayed by so many bishops which magnified the crisis into a public scandal?
