I have heard that he has an extremely violent temper. His wife is a frail person. When they are in public together, her body language is very stiff, almost like a frightened child. Sure, she smiles - but she is terrified of something.
Also, they sold their house in Cornville (ten minutes from where I live), and also put up their house in Phoenix for sale. Don't know if it sold or not, but it was way over two million, if I remember correctly.
She has had a problem with prescription drugs.
