BLOOMINGTON, Minn. — The Minneapolis airport’s governing board banned a video from President Trump’s homeland security chief that blamed Democrats for the federal government shutdown. The video had been playing at security checkpoint lines. The video was the latest evidence that former South Dakota Governor Kristi Noem, now Trump’s homeland security secretary, is incompetent. She narrates the 37-second video in clear violation of the 1939 Hatch Act, which forbids federal employees from such political activities. Other airports also have told their local federal security agents to take down the one-sided Noem video being forced on travelers. Meanwhile the federal shutdown entered its 14th day. Polls show most Americans blame Trump and Congressional Republicans for the shutdown.
