US President Donald Trump has announced a cabinet reshuffle that will see Kristi Noem move to a newly created diplomatic role after being removed as Secretary of the US Department of Homeland Security (DHS). Trump confirmed on Thursday that Oklahoma Senator Markwayne Mullin will be nominated to lead the department, marking the first major personnel change of the administration's second term.
The transition is scheduled to take effect on 31 March 2026. Noem will take up a position titled Special Envoy for the 'Shield of the Americas', a regional security programme focused on cooperation across the Western Hemisphere. Mullin, meanwhile, is expected to assume leadership of the federal agency responsible for border enforcement and domestic security if his nomination is confirmed.
