Trump fires Homeland Security Secretary Kristi Noem

President Donald Trump has fired his embattled Homeland Security Secretary Kristi Noem. Trump said he was nominating Oklahoma Republican Sen. Markwayne Mullin for the position in an announcement on social media on Thursday. The announcement came after Noem faced a two-day grilling on Capitol Hill from Republicans and Democrats and as Noem faced mounting criticism over her leadership of the Department of Homeland Security. Trump says he’ll make Noem a “Special Envoy for The Shield of the Americas.” Noem touted her achievements on social media and thanked Trump for the new role.
