CRUZ: I'm going to tell you what I really think of Donald Trump. This man is a pathological liar. He doesn't know the difference between truth and lies. He lies practically every word that comes out of his mouth. And in a pattern that I think is straight out of a psychology textbook, his response is to accuse everybody else of lying.

He accuses everybody on that debate stage of lying. And it's simply a mindless yell. Whatever he does, he accuses everyone else of doing. The man cannot tell the truth, but he combines it with being a narcissist. A narcissist at a level I don't think this country has ever seen.

Donald Trump is such a narcissist that Barack Obama looks at him and goes, 'Dude, what's your problem?' Everything in Donald's world is about Donald. And he combines being a pathological liar, and I say pathological because I actually think Donald, if you hooked him up to a lie detector test, he could say one thing in the morning, one thing at noon and one thing in the evening, all contradictory and he's pass the lie detector test each time. Whatever lie he's telling, at that minute he believes it.
