Washington D.C. – President Donald Trump removed Homeland Security Secretary Kristi Noem from her post on Thursday, a move culminating months of mounting criticism over her leadership, spending decisions, and conduct. The dismissal, confirmed by multiple sources, marks the most significant personnel shake-up of Trump’s second term and comes as the administration navigates escalating international tensions, including heightened conflict with Iran. The decision underscores a growing frustration within the White House regarding Noem’s performance and a desire to project stability amid increasing scrutiny.
The ousting of Noem follows a period of increasing turbulence, punctuated by contentious congressional hearings and reports detailing questionable use of department funds. Sources within the administration indicated that allies and advisors had repeatedly urged Trump to grab action, citing a loss of trust and a distraction from the administration’s core agenda. Trump announced his intention to nominate Oklahoma Senator Markwayne Mullin to replace Noem, effective March 31, 2026, praising Mullin as a “fiercely loyal” and “spectacular” choice for the role.
Congressional Scrutiny and Allegations of Mismanagement
The ice under Noem began to thin even before this week’s grilling by House and Senate committees, where she faced bipartisan questioning regarding alleged mismanagement within the Department of Homeland Security. Lawmakers pressed Noem on issues ranging from the agency’s shutdown to shootings involving federal agents, and the delayed disbursement of FEMA funds intended for disaster relief. She also faced scrutiny over a rumored extramarital affair with her de facto chief of staff, Corey Lewandowski, refusing to deny the allegations under oath.
A significant point of contention revolved around Noem’s authorization of over $270 million in funds to purchase two luxury Gulfstream jets and lease a Boeing Business Jet 737, ostensibly for deportation purposes. However, the 737’s lavish interior, featuring a bedroom and bar, raised eyebrows and sparked accusations of wasteful spending. According to reports, Noem and Lewandowski then extended the use of the 737 to First Lady Melania Trump for flights between Washington D.C. And New York, a move one administration official described as an “insurance policy.”
The Aircraft Deal and White House Concerns
The aircraft deal quickly became a focal point of criticism, with one administration official labeling it “the world’s worst deal to buy an aircraft.” Trump reportedly spoke with Lewandowski this week regarding the situation, a conversation described as “not a positive call.” The controversy surrounding the planes, coupled with the contentious congressional hearings, proved to be the final blow for Noem, whose standing with the President had already been eroded by her handling of an immigration crackdown in Minneapolis.
According to one Trump advisor, the Minneapolis operation was a “disaster,” resulting in the fatal shooting of two U.S. Citizens by federal agents. Noem also struggled to provide a satisfactory explanation for the continued delay in releasing FEMA funds earmarked for disaster relief. “She had no goodwill on Capitol Hill,” an advisor stated. “She mismanaged FEMA. She didn’t show up to hearings. She was disrespectful. No one liked her.”
Shifting Blame and a New Envoy Role
In announcing Noem’s departure, Trump framed the move as a transition to a new role: “Envoy for The Shield of the Americas,” leading a new security initiative in the Western Hemisphere. However, this move appeared to be largely cosmetic, intended to soften the blow of her dismissal. Trump also distanced himself from Noem’s controversial immigration ad campaign, which cost approximately $200 million, telling Reuters he “never knew anything about” it. This claim contradicts earlier reports indicating Trump had reviewed and even critiqued versions of the ads, requesting his image be prominently featured. As of Thursday, at least $79 million had been spent on airing the ads, according to data from AdImpact.
The White House hopes Noem’s removal will help break a congressional deadlock over DHS funding, particularly as the agency faces challenges amid escalating tensions with Iran. The shutdown has left the cybersecurity sub-agency with furloughed staff and others working without pay. Democrats, however, have indicated that Noem’s departure alone will not be sufficient to secure their support for funding. “Democrats were complaining about Noem. Now she’s gone,” an administration official said. “If they want to still fight the president at a time we need a fully funded Homeland Security department, especially after he made a personnel move they wanted, that’s on them to look unreasonable.”
The appointment of Senator Markwayne Mullin signals a desire for a more reliable and loyal figure at the helm of DHS. Mullin has been a consistent defender of the President and his immigration policies. The coming weeks will be critical as Mullin transitions into his new role and the administration seeks to address the ongoing funding challenges and security threats facing the nation. The long-term impact of Noem’s departure on the administration’s immigration agenda and overall security posture remains to be seen.
What comes next for the Department of Homeland Security will depend heavily on Senator Mullin’s ability to navigate the political landscape and address the pressing issues facing the agency. The confirmation process and subsequent implementation of his strategies will be closely watched by lawmakers, stakeholders, and the public alike.
