It is the Homeland Security Department that is charged with KEEPING OUT TERRORISTS. So of course shutting it down makes a lot of sense. The better to let terrorists sneak in as fast as they can to prove ultimatum boy's point. He is a**backwards on everything because he doesn't have a clue about the relationship between CAUSE AND EFFECT!
He does his foreign policy via tweets. He takes no responsibility for anything he does/says that goes WAY SOUTH on him. "WHO ME?" Nothing means anything to him. How weird that he could have lived to be so very old without understanding the way things work. Oh well. He had people who did his thinking for him.SIGH.
