“Michelle and the kids are wonderful in that if I said, ‘You know what guys, I want to do something different,’ they would be fine,’’ he said. “They’re not invested in daddy being president or my husband being president … If family is doing well and Michelle is still putting up with me, then I’ve got enough energy to keep doing the work that I’m doing.’’
