In a major shake-up within the U.S. government, President Donald Trump has removed Kristi Noem from her role as Secretary of the United States Department of Homeland Security (DHS) and nominated Oklahoma Senator Markwayne Mullin to replace her. Trump fires Kristi Noem
The decision, announced in early March 2026, came after weeks of political controversy, congressional scrutiny, and growing criticism over Noem’s leadership of the powerful security agency. The sudden move marks one of the most significant cabinet changes during Trump’s second presidential term.
Why Trump Fired Kristi Noem
Multiple factors contributed to Noem’s dismissal from the top homeland security position. While Trump praised some of her immigration enforcement efforts, reports suggest that several controversies and political pressures ultimately led to her removal.
1. Intense Congressional Hearings
One of the most immediate triggers was a heated congressional hearing in which Noem faced tough questioning from lawmakers. During the hearing, members of Congress challenged her policies, management decisions, and statements regarding DHS operations.
The tense exchange reportedly angered the White House and raised concerns about her ability to publicly defend the administration’s policies.
2. Controversial $220 Million Ad Campaign
Another major controversy centered on a $220 million advertising campaign promoting immigration enforcement and encouraging undocumented immigrants to self-deport.
Critics accused the campaign of being overly political and potentially benefiting Noem personally. The contract also drew scrutiny because it allegedly bypassed standard bidding procedures.
3. Fatal Enforcement Operations
The DHS also faced backlash after two U.S. citizens were fatally shot during federal enforcement operations in Minneapolis, which triggered public outrage and political criticism. Opponents argued that the incident showed failures in oversight and accountability within the agency.
4. Personal Controversies and Internal Tensions
Reports also mention internal conflicts within DHS leadership and allegations involving political adviser Corey Lewandowski. Questions about the relationship during a congressional hearing became a public controversy and reportedly worsened Noem’s standing with the administration.
5. Bipartisan Political Pressure
By early March 2026, both Democrats and some Republicans had begun criticizing Noem’s leadership, and calls for accountability were increasing. Facing mounting pressure, Trump decided to remove her from the cabinet position.
What Happens to Kristi Noem Now?
Although she was removed as DHS secretary, Noem was not completely pushed out of the administration.
Trump reassigned her to a newly created diplomatic role as Special Envoy for “The Shield of the Americas.” The position will focus on regional security cooperation in the Western Hemisphere.
This move allows the administration to maintain her involvement while shifting her away from the politically sensitive homeland security portfolio.
Who Is Markwayne Mullin?
Trump announced that Senator Markwayne Mullin will become the next DHS secretary, pending Senate confirmation.
Political Background
Mullin is the junior U.S. senator from Oklahoma and a member of the Republican Party. Before entering the Senate in 2023, he served nearly a decade in the U.S. House of Representatives, representing Oklahoma’s 2nd congressional district.
Known as a strong supporter of Trump’s “America First” agenda, Mullin has consistently backed strict border policies and aggressive immigration enforcement.
Business and Personal Life
Before politics, Mullin worked in his family’s plumbing business and eventually ran the company. He also hosted a home improvement radio show in Oklahoma.
Interestingly, Mullin is one of the few U.S. senators without a bachelor’s degree, holding an associate degree in construction technology instead.
He is also a member of the Cherokee Nation and has six children.
Political Reputation
Mullin has built a reputation as a combative and outspoken conservative. Supporters view him as a strong defender of law enforcement and border security, while critics say his aggressive rhetoric can be polarizing.
Trump praised Mullin as a loyal ally and said he would help keep the country safe and secure.
What Mullin’s Appointment Could Mean for DHS
If confirmed by the Senate, Mullin will take control of one of the most powerful federal agencies. DHS oversees:
- U.S. Border Patrol
- Immigration and Customs Enforcement (ICE)
- Transportation Security Administration (TSA)
- Federal Emergency Management Agency (FEMA)
Experts believe Mullin will likely continue Trump’s hardline immigration policies, including stronger border enforcement and expanded deportation efforts.
However, the Senate confirmation process could become contentious, as Democrats are expected to closely examine his views and policy plans.
Political Impact of the Cabinet Shake-Up
Noem’s firing highlights the high-stakes political environment surrounding immigration and national security in the United States.
For Trump, replacing a cabinet member early in his second term signals a desire to reassert control over policy direction and avoid political distractions. For DHS, the leadership change could reshape how the agency handles border security, immigration enforcement, and disaster response.
With immigration remaining one of the most divisive issues in American politics, Mullin’s nomination ensures that debates over homeland security policy will continue in Washington.
