Trump reshuffles DHS leadership, naming Mullin to replace Noem

President Trump announces Kristi Noem will be replaced as Homeland Security Secretary by Senator Markwayne Mullin by the end of March, with Noem moving to a new role as Special Envoy for the Shield of the Americas; Corey Lewandowski is also leaving DHS. The White House backs Mullin and will push for a quick confirmation, while Democrats call for broader DHS reform. Mullin says he’ll work to earn votes and keep the homeland secure. This marks the administration’s first major cabinet departure and signals a shift in immigration policy.
