5 controversies that dogged Noem's DHS tenure

Kristi Noem is on her way out at the Department of Homeland Security after a tenure marred by personal controversies and an unpopular immigration crackdown. The big picture: Noem has long been a target for Democrats, but her leadership also angered some congressional Republicans. She becomes the first Cabinet secretary to be removed from their post in President Trump's second term. Driving the news: Trump announced Thursday that he plans to tap Sen. Markwayne Mullin (R-Okla.) to replace Noem.
