WASHINGTON — President Donald Trump announced Thursday he is replacing Homeland Security Secretary Kristi Noem with Oklahoma Senator Markwayne Mullin, a move that comes after Noem faced scrutiny from lawmakers over departmental spending and immigration enforcement policies. The decision marks the first departure of a cabinet secretary during Trump’s second term.
The announcement, made via social media, follows a contentious congressional hearing earlier this week where both Republican and Democratic members questioned Noem about a $220 million Homeland Security advertising campaign featuring her prominently, as well as the department’s handling of border security and disaster response. Trump stated he will appoint Noem as a “special envoy for The Shield of the Americas,” a new security initiative focused on the Western Hemisphere, according to USA Today.
Senator Mullin’s nomination is subject to Senate confirmation, but a federal law allows him to serve in an acting capacity while the process is pending. Speaking to reporters shortly after the announcement, Mullin said he was “excited” about leading the Department of Homeland Security and “ready to gain started,” ABC News reported. He acknowledged he has “no idea” how quickly his confirmation will proceed.
Noem’s Tumultuous Tenure
Noem’s departure caps a period of significant challenges for the Department of Homeland Security. She faced criticism over the agency’s spending, particularly the advertising campaign and its handling of immigration enforcement. Frustrations mounted following the shooting deaths of two U.S. Citizens in Minneapolis, which prompted scrutiny of the department’s tactics and leadership. The Washington Examiner noted that public support for Trump’s immigration agenda had declined over the past year amid these controversies.
Beyond immigration, Noem similarly drew criticism from both sides of the aisle regarding the pace of emergency funding disbursement through the Federal Emergency Management Agency (FEMA) and the administration’s response to various disasters. These issues contributed to a growing sense of unease within the administration and among some Republicans in Congress.
In a post on X (formerly Twitter), Noem thanked President Trump for the new appointment and highlighted what she described as her accomplishments at the Department of Homeland Security.
Thank you @POTUS Trump for appointing me as the Special Envoy for the Shield of the Americas. @SecRubio and @SecWar are incredible leaders and I look forward to working with them closely to dismantle cartels that have poured drugs into our nation and killed our children and…

Mullin to Lead DHS Amid Ongoing Challenges
Senator Mullin will take the helm of the third-largest department in the U.S. Government, tasked with implementing President Trump’s hardline immigration agenda. During the first year of Trump’s administration, immigration enforcement was characterized by high-profile operations, often led by Border Patrol commander Gregory Bovino, reporting directly to Noem. These operations, while intended to showcase the administration’s commitment to border security, frequently resulted in clashes with activists and protesters, drawing criticism and fueling opposition to the president’s policies.
The change in leadership comes as parts of the Department of Homeland Security are currently facing a shutdown due to a funding dispute over Immigration and Customs Enforcement (ICE). Democrats have indicated they will only fund the department if changes are made to ICE in the wake of recent shooting deaths, CNBC reported.
California Governor Gavin Newsom seized on Noem’s firing, stating, “Donald Trump is in retreat,” and characterizing it as the first dismissal of a high-profile cabinet member during Trump’s second term.
The Senate will now consider Mullin’s nomination, and his confirmation process is expected to be closely watched. The Department of Homeland Security faces ongoing challenges related to border security, disaster response, and funding, and Mullin’s leadership will be critical in navigating these issues in the coming months. The focus will be on how he intends to address the ongoing funding fight and implement the administration’s immigration policies.
