WASHINGTON — President Donald Trump announced on Thursday, March 5, 2026, the removal of Kristi Noem as Secretary of Homeland Security, a move that follows mounting criticism of her leadership and enforcement tactics. Senator Markwayne Mullin of Oklahoma, a staunch Trump ally, will replace her, the President announced via a post on Truth Social.
According to the announcement, Noem will transition to a novel role as Special Envoy for The Shield of the Americas, a new security initiative in the Western Hemisphere set to be unveiled on Saturday, March 8, 2026, in Doral, Florida. “I thank Kristi for her service at ‘Homeland,’” Trump wrote. The Department of Homeland Security did not immediately respond to requests for comment.
Noem’s tenure, which began shortly after Inauguration Day, was marked by a focus on aggressive immigration enforcement. She frequently visited federal agencies and personnel across the country, often wearing the uniforms of the agencies she was visiting, including those of the TSA, Border Patrol, and the U.S. Coast Guard. While some praised her visibility and support for the workforce, others criticized the practice as unserious.
The change in leadership comes after a contentious week of Congressional hearings and months of speculation surrounding Noem’s departure. Critics have raised concerns about the department’s immigration policies, while internal disagreements reportedly existed regarding the administration’s mass deportation agenda. Sources indicate that Noem and senior advisor Corey Lewandowski prioritized the sheer number of arrests and deportations, potentially clashing with other officials like White House border czar Tom Homan.
During her time as Secretary, Noem participated in ICE raids, such as one in New York City, and made multiple visits to the U.S.-Mexico border, including the San Ysidro Port of Entry in California in March 2025. She was often seen in uniform during these operations. Images from her tenure highlight her frequent presence alongside ICE and CBP personnel.
The removal of Noem and the appointment of Mullin signal a continued emphasis on strict immigration control. Mullin stated he would focus on “protecting the homeland” upon learning of his nomination. This development underscores the Trump administration’s ongoing commitment to reshaping immigration and border policy. The Associated Press reported on the announcement and the reactions from Capitol Hill.
The relationship between Noem and Lewandowski was also subject to scrutiny, with reports of a “contentious” meeting with President Trump in September. Wired Magazine detailed the controversies surrounding Noem’s time in office, including these internal dynamics.
