Kristi Noem was removed as Department of Homeland Security Secretary following allegations of obstructing an inspector general's investigation and creating security risks, with Senator Markwayne Mullin confirmed as her replacement by a 54-45 Senate vote on March 24, 2026. Noem faced intense scrutiny for systematically obstructing the DHS Inspector General's work and failing to address "significant" security risks from a relaxed airport screening policy. President Trump nominated Oklahoma Senator Markwayne Mullin, a former MMA fighter, who underwent a mixed confirmation hearing addressing his vision, past comments, and previously undisclosed travel. Mullin's confirmation by the Senate finalized the leadership transition at the Department of Homeland Security, concluding a period of internal agency turmoil.
