WASHINGTON - Event date: March 5, 2026. Donald Trump has removed Kristi Noem as secretary of Homeland Security and nominated Oklahoma Senator Markwayne Mullin to take her place, according to the packet’s source.
The decision ends Noem’s 13-month run at the department and appears to follow a long stretch of strain around DHS, including budget fights, immigration enforcement battles and questions about how the department was being run. Trump said Noem would move into a new role as special envoy for what he called The Shield of the Americas, a security initiative aimed at the Western Hemisphere.
The report says Noem learned she was being replaced shortly before appearing at a law-enforcement conference in Nashville. Trump made the announcement on Truth Social while she was on stage. The source also says her departure is effective March 31, giving the administration a short transition window.
Mullin’s nomination is notable for political and symbolic reasons. He has served in the Senate since 2023 and, if confirmed, would become the first Native American to lead DHS. Trump praised him as a MAGA warrior and said he had the temperament and knowledge needed to advance the administration’s agenda.
The timing of the reshuffle matters. Noem had just faced two days of aggressive congressional hearings, where lawmakers from both parties pressed her on the fatal shootings of protesters in Minnesota, the department’s ad spending and the handling of contracts connected to people around her office. The Independent’s report describes those hearings as part of the backdrop to her removal.
The department itself has also been under pressure because of the continuing funding lapse and deeper policy fights over immigration enforcement. DHS under Noem expanded detention capacity and rapidly hired new officers, but those actions also produced lawsuits and political backlash. That conflict made the secretary one of the most visible and controversial figures in the administration.
For Trump, the change offers a chance to reset a department central to his immigration agenda. For Noem, the replacement turns a high-profile cabinet post into a new foreign-policy style assignment. For Mullin, it is a chance to move from Senate politics to one of the most difficult jobs in the federal government. The fight over DHS is not ending with the personnel shift; it is simply changing hands.
The personnel change is also a sign that immigration enforcement remains at the center of Trump’s domestic agenda. DHS has become the main instrument for detention, deportation and border policy, so a change in secretary is not just an administrative reshuffle. It can alter how aggressively the department carries out the White House’s priorities and how it answers congressional oversight.
Noem’s exit after a series of high-profile hearings suggests that the administration may be trying to trade controversy for control. Whether Mullin can calm the department while still satisfying the president’s instincts for hard-line enforcement will be the question if he moves forward in the confirmation process.
For Congress, the nomination will likely reopen questions about how much influence the White House wants over the department and how much independent oversight lawmakers can still exert. The replacement does not end the political fight around DHS; it simply moves the argument into a new confirmation battle.
