Kevin McAleenan to Become Acting Homeland Security Secretary After Kirstjen Nielsen Resigns

President Trump announced Sunday that Kevin McAleenan, the current U.S. Customs and Border Protection Commissioner, will become the Acting Homeland Security Secretary in the wake of Kirstjen Nielsen’s Sunday resignation. “I have confidence that Kevin will do a great job!” Trump wrote. The announcement comes just seconds after the president announced Nielsen’s departure on Twitter and thanked her “for her service.” It’s not yet clear exactly when Nielsen is leaving the role.
