"There's a mental health problem in Congress," says actor and liberal activist Sean Penn. The president could solve the problem "by committing them by executive order," Penn told CNN's Piers Morgan Monday night.Asked if Penn would have "people like Ted Cruz" committed, Penn said, "He is my American brother. I won't -- I think we should take care of him, he is in, he's the trouble.""Well, actually have him committed," Morgan followed up."Yeah, I think it's a good idea," Penn said.
