Cabinet Shake-Up Follows Mounting Controversies At Homeland Security; Transition Set For March 31st

Thursday, March 5, 2026,  3:35 P.M. ET. 5 Minute Read, By Jennifer Hodges, Political Editor: Englebrook Independent News,

WASHINGTON, DC.- President Donald Trump announced Thursday that he will remove Kristi Noem as Secretary of the United States Department of Homeland Security and nominate Markwayne Mullin to lead the sprawling national security agency.

     The leadership change, confirmed by the White House and the president himself, will take effect March 31, 2026, pending Senate confirmation of Mullin.

     Trump revealed the decision in a post on Truth Social, where he praised Mullin as a loyal ally and strong advocate for border security, and thanked Noem for her service in the administration.

     In his statement, Trump wrote that Mullin is:

     “a strong patriot who understands the importance of protecting our borders and our homeland, and he will do an incredible job leading the Department of Homeland Security.” 

     The president added that Noem would be transitioning to another role connected to Western Hemisphere security cooperation. However, details about the position have not yet been fully outlined by the administration.

     Multiple sources familiar with the matter confirmed that Trump personally informed Noem of the decision last Saturday during a conversation at the president’s Mar-a-Lago residence in Florida, several days before the public announcement.

Turbulent Tenure At Homeland Security;

     Noem, the former two-term governor of South Dakota, was confirmed as Secretary of Homeland Security in early 2025 at the start of Trump’s second presidential term.

     During her time leading the department, she became a prominent defender of the administration’s immigration enforcement policies and border security initiatives.

     However, her tenure increasingly came under scrutiny in recent months amid several political controversies and congressional investigations.

Inspector General Oversight Disputes;

     One of the most significant issues involved tensions between DHS leadership and the department’s Office of Inspector General. Federal watchdog officials alleged the department had “systematically obstructed” certain oversight requests tied to internal investigations.

     The dispute led to heated exchanges during congressional hearings, where lawmakers from both parties pressed Noem about transparency and departmental management.

Advertising Campaign Controversy;

     Another controversy centered on a $200-plus million DHS public-relations campaign that prominently featured Noem in a series of promotional advertisements.

     During testimony before lawmakers, Noem suggested the campaign had been approved at the highest levels of the administration.

     Trump later publicly contradicted that assertion, stating that he had not personally authorized the campaign, intensifying political pressure on the secretary.

Immigration Enforcement Debates;

     The department’s aggressive enforcement operations also generated significant political debate.

     Supporters of the administration argued the policies were necessary to combat illegal immigration and dismantle transnational criminal networks operating along the southern border.

     Critics, including several civil-rights organizations, argued that some tactics raised concerns about detention conditions and the treatment of migrants.

     Among the most widely discussed initiatives was a multi-agency crackdown targeting organized criminal groups operating in major American cities.

Renewed Personal Scrutiny;

     Noem also faced renewed criticism stemming from a widely discussed anecdote in her memoir describing the euthanizing of a farm dog that she said could not be trained.

     The episode resurfaced during recent hearings and became a flashpoint for critics questioning her judgment, though supporters dismissed the controversy as politically motivated.

Trump Ally Chosen To Lead DHS;

     Trump’s selection of Mullin reflects the president’s continued emphasis on loyalty and alignment with his national security agenda.

     Mullin currently represents Oklahoma in the United States Senate, having won a special election in 2022 to replace longtime Senator Jim Inhofe.

     Before entering the Senate, Mullin served for a decade in the United States House of Representatives, representing Oklahoma’s 2nd Congressional District from 2013 to 2023.

     A businessman prior to entering politics, Mullin built and operated a successful plumbing company before launching his political career.

     He is also a citizen of the Cherokee Nation, making him one of the few Native Americans currently serving in the U.S. Senate.

     Throughout his time in Congress, Mullin has been a vocal supporter of Trump’s policies on border enforcement, immigration control, and national security.

     His strong alignment with the administration is expected to ease his transition into the cabinet role should he be confirmed by the Senate.

One Of The Government’s Largest Departments;

     The Department of Homeland Security is one of the largest agencies in the federal government, employing more than 250,000 personnel across multiple divisions.

     The department oversees numerous critical agencies and missions, including:

• U.S. Customs and Border Protection
• U.S. Immigration and Customs Enforcement
• Federal Emergency Management Agency
• United States Secret Service
• Transportation Security Administration

     Its responsibilities range from border enforcement and counterterrorism to disaster response, cybersecurity protection, and safeguarding the nation’s infrastructure.

Confirmation Process Ahead;

     If confirmed by the Senate, Mullin would take office March 31, 2026, the same day Noem is expected to formally depart the post.

     The White House has not yet announced a timeline for Mullin’s confirmation hearings, though they are expected to begin in the coming weeks.

     Meanwhile, administration officials have indicated that more information about the proposed “Shield of the Americas” initiative and Noem’s expected role within it will be released at a later date.
