I'm not going to tell you I know George W. Bush intimately. I'm not going to tell you we're best friends. I'll tell you I met him on a number of occasions. You know what? George W. Bush is a very nice guy. Very funny guy. His wife is a very nice woman; I thought she was a great first lady. George [W.] Bush was the worst president in the history of the United States of America... The issue is not Bernie Sanders. The issue is the Koch brothers. The issue is who owns America.
