Mullin Assumes DHS Leadership Amid Unpaid Employee Crisis.

The Homeland Security Department is about to get a brand new boss, and it's a move that could shake things up in a big way. Markwayne Mullin, a Republican senator from Oklahoma, just got confirmed in a 54-45 Senate vote, and he's set to take over the role from Kristi Noem. But here's the thing: Mullin's confirmation comes at a time when the department is in total chaos, with funding lapsed and more than 100,000 employees working without pay.
