WASHINGTON, D.C. March 5, 2026 – President Donald Trump announced on Thursday that he is replacing Department of Homeland Security (DHS) Secretary Kristi Noem with Republican Sen. Markwayne Mullin of Oklahoma, effective March 31, 2026. Noem, the former governor of South Dakota, will transition to a new role as special envoy for “The Shield of the Americas,” a newly created initiative focused on security in the Western Hemisphere.
The shake-up comes amid intense scrutiny of Noem’s tenure, which has been marked by controversies including the handling of immigration enforcement and disaster response efforts. Critics, including some Republicans, have pointed to a $220 million advertising campaign encouraging undocumented immigrants to self-deport, which Trump reportedly did not approve. Additionally, the fatal shootings of two U.S. citizens during protests in Minneapolis by immigration officers under DHS oversight drew widespread condemnation. Noem faced blistering questions from lawmakers during recent congressional hearings, where she defended her actions but acknowledged ongoing challenges.
Shortly after the announcement, Noem addressed a gathering of law enforcement leaders in Nashville, Tennessee, in what appeared to be her first public appearance since the news broke. In her remarks, she did not directly reference her impending departure but emphasized the critical role of DHS in protecting American citizens and upholding constitutional priorities. “The Constitution demands we treat our citizens’ way,” Noem stated, highlighting the department’s formation post-9/11 and its diverse agencies, including CBP, ICE, FEMA, and CISA.
Noem praised the bravery of first responders, referencing a recent attack in Austin, Texas, where law enforcement’s quick actions saved lives despite the loss of three individuals. Quoting George Orwell, she noted, “People sleep peacefully in their beds at night only because rough men stand ready to do violence on their behalf.” She also addressed ongoing challenges, such as judicial interference and sanctuary cities, and invited questions on how to better support frontline officers.
Sen. Mullin, a former mixed martial arts fighter and businessman, has served in the Senate since 2023 and is known for his tough stance on immigration and national security. His nomination requires Senate confirmation, but under federal law, he could serve in an acting capacity pending approval. Trump described Mullin as “highly respected” in his Truth Social post, signaling confidence in his ability to lead the department.
This marks the first major Cabinet change in Trump’s second term, reflecting shifting priorities as the administration grapples with border security, cyber threats, and emergency preparedness. Noem’s departure caps a turbulent period for DHS, which has also faced a partial shutdown lasting 20 days, impacting operations though many employees continued working without pay.
