- President Trump removed Kristi Noem as Secretary of Homeland Security, nominating Senator Markwayne Mullin as her successor.
- FEMA officials expressed relief, citing months of operational upheaval and restrictive micromanagement under Noem’s controversial tenure.
- Noem will transition to a Special Envoy role for the Shield of the Americas security initiative.
(UNITED STATES) — President Donald Trump removed Kristi Noem as Secretary of Homeland Security and nominated Senator Markwayne Mullin of Oklahoma to replace her, a DHS leadership change that drew sharp reactions inside FEMA and renewed scrutiny of how the department balances border enforcement with disaster response.
Trump announced the move on March 5, 2026, and said Noem will shift into a new role as Special Envoy for The Shield of the Americas, a Western Hemisphere security initiative.
Inside the Federal Emergency Management Agency, current and former officials described relief at Noem’s departure after months of upheaval, restructuring and disputes over management controls that they said slowed day-to-day operations.
The backlash followed a run of controversies that Reuters reported included scrutiny over department spending, the deaths of two U.S. citizens during federal enforcement operations in Minneapolis, and broader criticism of Noem’s hardline approach to immigration and homeland security policy.
The Guardian reported on March 6 that some FEMA staffers said Noem’s tenure made the United States less safe by shrinking the agency and imposing heavy-handed oversight on its operations. Former FEMA chief of staff Michael Coen told the paper that Noem’s “micromanagement of Fema eroded Fema’s capability and withheld critical funding from states and communities across the country.”
FEMA’s internal mood reflected worries about disaster readiness, staffing and funding decisions that employees and former officials tied to the department’s sign-off rules and budget pressure during Noem’s tenure.
Earlier Guardian coverage said FEMA lost roughly a third of its full-time staff through firings, resignations and retirements, while federal preparedness funding also fell.
In January 2026, the paper reported outrage among current and former FEMA employees over plans to eliminate thousands more positions as part of a broader restructuring effort linked to Noem’s leadership.
Noem’s critics inside FEMA also pointed to procurement and approval bottlenecks. Under her tenure, she implemented a policy requiring her personal sign-off on any expenditure over $100,000, a threshold that former officials and staff said forced routine operational decisions upward.
Former officials argued that the extra layer of review hampered surge capacity and slowed deployments when disasters required rapid contracting, staffing and logistics moves.
Staffing strains became a recurring theme in the criticism. FEMA reportedly recorded an 18% departure rate among permanent full-time staff during Noem’s tenure, a churn level that current and former officials said risked hollowing out institutional knowledge.
State and local officials also watched the department’s financial pipeline. FEMA carried a reported $17 billion backlog in disaster reimbursements, a slowdown that can leave states and localities waiting longer for federal dollars tied to response and recovery costs.
Noem also faced scrutiny over a high-profile spending dispute. A $220 million taxpayer-funded ad campaign featuring Noem on horseback became a flashpoint for political and management criticism, and it emerged as a primary trigger cited for her removal.
The controversy widened after Noem said President Trump approved the campaign, while Trump later denied any knowledge of it.
DHS and its leadership offered a sharply different account of Noem’s record. In an official department press release dated March 5, 2026, DHS said: “Under the leadership of Secretary Kristi Noem, the Department of Homeland Security had its most successful period ever. Secretary Noem delivered on that promise [of securing the border]. We now have the most secure border in U.S. history.”
DHS published the statement in a post titled “Thanks to President Trump and Secretary Noem, America is Safer”.
Noem also struck a celebratory note in her farewell message to DHS staff, which the department posted on March 5, 2026. “It has been the honor of my life to serve as the Secretary of the Department of Homeland Security and lead you. FEMA delivered disaster relief at a 100% faster rate, we ushered in the golden age of travel, saved the American taxpayer $13 billion and revitalized the U.S. Coast Guard.”
DHS posted that note under “Message from Secretary Kristi Noem”.
Trump, in his own announcement via social media, praised Noem’s “spectacular results (especially on the Border!)” even as he nominated Mullin and said the senator would “restore operational discipline.”
The nomination set up a transition that, even if smooth, leaves DHS with overlapping pressures from immigration enforcement and emergency management at the same time.
DHS oversees immigration agencies including USCIS, ICE and CBP, while FEMA sits inside the department and coordinates federal disaster response, emergency funding and national preparedness.
For immigration and policy watchers, the change matters because a shift at the top can affect both enforcement posture and the mechanics of humanitarian and emergency operations, including travel disruptions and disaster relief in communities with large immigrant populations.
Reuters reported that Trump’s administration plans to continue an aggressive immigration enforcement agenda under the strong influence of top adviser Stephen Miller, a signal that personnel changes may alter management style more than policy direction.
Even so, FEMA staff and former officials said management style and approval chains can shape outcomes in practical ways during crises, when speed, procurement and funding approvals often determine how quickly resources move.
The Minneapolis enforcement operation that Reuters cited as part of the controversy around Noem’s tenure drew particular attention because it blended immigration enforcement tactics with broader public safety consequences.
The operation, “Operation Metro Surge,” resulted in the fatal shootings of two U.S. citizens, Renee Good and Alex Pretti, by federal agents, and the episode sparked national outrage, the account said.
The same summary described a partial DHS funding shutdown by Democrats in Congress, underscoring how department actions and political blowback can collide with basic operational needs.
Associated Press reporting also placed Noem’s removal in the context of local fallout. The agency said Minneapolis residents and immigrant communities continued to deal with the consequences of the immigration crackdown under Noem’s watch, while local advocates argued her removal did not undo harm already done.
That dynamic left DHS and FEMA facing different audiences at once: immigrant communities tracking enforcement intensity, and states and localities tracking whether disaster staffing and reimbursements stabilize.
The coming weeks now hinge on confirmation politics and internal directives as much as on headlines. Mullin’s nomination requires Senate action, and the handoff also intersects with authority over approvals and sign-offs that FEMA staff criticized.
Even before any leadership handover takes effect, the department must manage day-to-day choices about internal controls, disaster spending and staffing levels that employees said became harder under Noem.
Some of the sharpest internal complaints centered on micromanagement and morale. The Guardian’s March 6 report said staffers were “celebrating” the firing and described Noem as a “singularly destructive force.”
Coen’s criticism to the paper focused on the mechanics of capability, describing withheld funding and a weakened operational posture.
DHS did not frame the leadership shift as a rebuke. Its official narrative emphasized border security and broader departmental gains, while Noem’s farewell message cited faster disaster relief and large cost savings.
The disagreement over performance also reflects how DHS measures success differently across missions. Border security metrics and enforcement actions draw intense political attention, while FEMA’s performance often shows up in response times, reimbursements and staffing stability.
Operationally, FEMA staff and former officials said they will watch whether the next DHS secretary changes spending-approval rules that determine how quickly FEMA can move money and resources.
Reimbursement flow will remain a practical test for states and localities. A backlog can push recovery timelines and strain local budgets while communities wait for federal payments tied to repairs and rebuilding.
Staff retention will be another measure. FEMA’s reported 18% departure rate and the Guardian’s earlier account of losing roughly a third of full-time staff raised concerns about whether the agency can maintain surge capacity without experienced personnel.
The ad-campaign controversy will also linger as a management lesson inside DHS. The $220 million price tag and the public dispute over whether Trump approved it turned routine messaging and branding decisions into a defining fight over oversight and spending priorities.
Noem’s new assignment adds another layer to the reshuffle. Trump said she will serve as Special Envoy for The Shield of the Americas, and the State Department also publicized the initiative in a March 6, 2026 announcement titled “U.S. to Host Shield of the Americas Summit”.
The personnel moves now create a short transition window in which FEMA officials, DHS components and outside partners must plan around who holds authority for final approvals, especially for large expenditures and disaster funding decisions.
The timing matters for continuity of operations and chain of command, because DHS leadership can influence not only policy posture but also the pace of sign-offs that govern procurement, staffing moves and reimbursements.
Trump’s announcement included both confirmed steps and pending ones. Noem’s removal and her new assignment came directly from the president, while Mullin’s move into the role depends on Senate confirmation.
For DHS employees and state emergency managers, the practical question is whether the department maintains tight centralized controls or delegates more authority back to FEMA’s operational leadership.
Communities affected by immigration enforcement will also monitor whether the next DHS secretary changes tactics, even as Reuters reported the administration expects to keep pursuing a hardline agenda shaped by Stephen Miller.
The larger picture remains that DHS carries two missions that can collide in public attention: immigration enforcement and FEMA disaster coordination.
Leadership instability at DHS can ripple into both, shaping how aggressively immigration operations proceed and how quickly FEMA can obligate funds, deploy teams and close out reimbursements.
For residents in disaster-prone states, even incremental shifts in staffing, morale and approval speed can influence what help arrives and when.
For immigrant communities, changes in leadership can coincide with shifts in enforcement intensity, the conduct of operations, and the way federal actions affect local trust and daily life, even if top-level policy direction stays consistent.
As the transition unfolds, one divide stands out in the record so far: DHS and Noem publicly claimed major gains, while FEMA staff and former officials described disruption, slowed operations and reduced readiness, a clash that will follow the next leader into the job.
