Lou Dobbs: Obama should be "brought back" by U.S. Marshals after criticizing Trump abroad

“I think U.S. Marshals should follow him, and any time he wants to go follow the President like he is, and behave… I mean, this is just bad manners. It’s boorish, it’s absurd, he doesn’t realize how foolish he looks. I mean, he should be brought back by the Marshals. Isn’t there some law that says presidents shouldn’t be attacking sitting presidents?”
