Noem Out at DHS

President Donald Trump has fired his Homeland Security Secretary Kristi Noem, after mounting criticism over her leadership of the department, including the handling of the administration's immigration crackdown and disaster response. Trump, who said he would nominate in her place Oklahoma Republican Sen. Markwayne Mullin, made the announcement on social media on Thursday, two days after Noem faced a grilling on Capitol Hill from GOP members as well as Democrats.  Trump says he'll make Noem a "Special Envoy for The Shield of the Americas," a new security initiative that he said would focus on the Western Hemisphere.
