Art of the Deal co-author Tony Schwartz appeared on an MSNBC panel with Michael Cohen and Anthony Scaramucci to discuss what they understand about President Donald Trump and his psychology.

Schwartz, who said that the only reason he wrote the book was for money, explained that the people that are endeared to Trump are primarily those who never felt good enough as young boys.

"First, it is mostly men," said Schwartz. "Women are overwhelmingly against Trump. There is a disease that especially afflicts men and, most of all, men who grow up with a feeling of not being good enough. The disease of trying to win from the outside world through money and power and fame the love and recognition that was missing for them when they grew up in their own families. It is the heart of why Trump does what he does. He's still trying to prove his worth to his daddy. It is the story I tell about myself in Dealing with the Devil. I suspect it's true. I don't know. I suspect it is true for Michael and Anthony."
