Senator Markwayne Mullin was confirmed as the new Secretary of the Department of Homeland Security by a 54-45 Senate vote, replacing Kristi Noem amid controversy over her leadership. Mullin’s appointment comes during a prolonged DHS shutdown caused by Democratic demands for immigration enforcement reforms, which remain unresolved despite the leadership change. Known for bipartisan relationships, Mullin has pledged to empower personnel and implement policy shifts such as requiring judicial warrants for enforcement actions, while his confirmation drew both cross-party support and criticism.
