Trump fires DHS Secretary Kristi Noem, names Sen. Markwayne Mullin as replacement

President Trump has fired DHS Secretary Kristi Noem and appointed Senator Markwayne Mullin as the new DHS secretary, citing dissatisfaction with her testimony on a $220 million ad campaign. This leadership change at DHS, which oversees immigration enforcement, border security, and USCIS, could signal shifts in immigration policy implementation under the Trump administration. The move was announced via Truth Social on March 31, 2026.

In a statement posted to Truth Social, Trump dismissed current DHS Secretary Kristi Noem and named Sen. Markwayne Mullin (R-OK) as her replacement, reportedly due to unhappiness with her handling of testimony regarding a $220 million ad campaign related to DHS operations. Noem responded by claiming the administration had delivered the 'most secure border' in history. This abrupt change in DHS leadership, the agency central to immigration enforcement, deportations, ICE actions, and border policies, may impact ongoing Trump administration priorities like mass deportations and border security enhancements.
