Markwayne Mullin confirmed as Homeland Security Secretary amid shutdown and border challenges.

The U.S. Senate has confirmed Markwayne Mullin, a Republican senator from Oklahoma, as Secretary of Homeland Security, succeeding Kristi Noem. His confirmation, passed along party lines, comes amid ongoing challenges including border security, immigration enforcement, and operational disruptions at agencies like TSA and ICE. Mullin, known for his conservative stance on immigration and border policy, will lead the department during a federal shutdown that has left 100,000 employees unpaid. His appointment reflects a shift in priorities under President Trump’s second term, with expectations for stronger enforcement and reforms to national security and emergency response systems.
