US President Donald Trump has appointed Republican senator Markwayne Mullin as the new Secretary of Homeland Security, moving to replace Kristi Noem amid ongoing criticism of the department's leadership.
The 48-year-old Oklahoma lawmaker will oversee the cabinet-level agency during a partial government shutdown that has currently paused its funding. If confirmed by his peers in the US Senate, Mullin will become the first Native American to serve as Homeland Security secretary since the post was established in 2003.
