WASHINGTON — In the first major cabinet upheaval of his second term, President Donald Trump announced Thursday that Kristi Noem will step down as Secretary of the Department of Homeland Security (DHS) effective March 31. Trump has tapped Republican Senator Markwayne Mullin of Oklahoma to lead the agency, signaling a shift in leadership following Noem’s contentious week on Capitol Hill.
The transition, announced via Truth Social, comes amid reports of presidential dissatisfaction with Noem’s recent testimony and a burgeoning controversy surrounding a multi-million dollar taxpayer-funded advertising campaign.
A Strategic Reassignment Amid Growing Friction
President Trump framed the departure not as a firing, but as a transition to a new international role. Noem is slated to become the Special Envoy for “The Shield of the Americas,” a fresh security initiative focused on the Western Hemisphere.
“I am pleased to announce that the Highly Respected United States Senator from the Great State of Oklahoma, Markwayne Mullin, will become the United States Secretary of Homeland Security,” Trump wrote, adding that the details of the new initiative would be unveiled this Saturday in Doral, Florida.
Despite the President’s public praise for Noem’s “spectacular results” at the border, the move follows a disastrous week of oversight hearings. Reports surfaced Thursday via The Wall Street Journal suggesting Trump was “not happy” with Noem’s performance before the House and Senate Judiciary Committees.

Testimony and Taxpayer Scandals
The Secretary’s standing within the administration appeared to fracture during two days of heated questioning. Lawmakers grilled Noem on:
- Aggressive Enforcement: Intense scrutiny regarding the fatal shootings of Renée Good and Alex Pretti in Minnesota during DHS immigration enforcement actions.
- The “Mount Rushmore” Ad Campaign: A $200 million taxpayer-funded campaign encouraging self-deportation. The ads, featuring Noem on horseback, were criticized as self-promotional.
- Contracting Ethics: A ProPublica investigation previously alleged that DHS bypassed competitive bidding to award ad contracts to firms with personal ties to Noem.
The friction reached a breaking point when Noem claimed the President had personally signed off on the ad campaign. Trump pointedly disputed this to Reuters on Thursday morning, stating, “I never knew anything about it.”
Markwayne Mullin: From the Senate to the Cabinet
Senator Markwayne Mullin, a staunch Trump ally known for his confrontational style, is poised to take the helm of the $60 billion agency. A member of the Cherokee Nation, Mullin served a decade in the House before his 2022 election to the Senate.
Mullin’s background is unconventional for a DHS Secretary; he is the only sitting senator without a college degree, having built a career in his family’s plumbing business and as a radio host before entering politics. His reputation for aggressive rhetoric aligns with the administration’s “tough-on-the-border” stance, though he will face a rigorous confirmation process as the administration seeks to stabilize the department.
Looking Ahead
The official launch of “The Shield of the Americas” this weekend will provide more clarity on Noem’s new portfolio. Meanwhile, Mullin’s nomination moves to the Senate, where he is expected to face questions regarding his lack of traditional administrative experience and his plans to manage the ongoing border security operations that defined his predecessor’s short, turbulent tenure.
