Donald Trump Fires Homeland Security Secretary Kristi Noem After Combative Congressional Hearings
President Donald Trump will nominate Senator Markwayne Mullin to replace the Homeland Security secretary Her ouster followed two days of intense, bipartisan congressional hearings criticizing DHS leadership
Trump cabinet reshuffle
President Trump fired Homeland Security Secretary Kristi Noem and named Sen. Markwayne Mullin his preferred replacement.
“President Trump fired Homeland Security Secretary Kristi Noem, tapped Sen. Markwayne Mullin as his preferred replacement and named Noem a special envoy for a new ‘Shield of the Americas’ initiative, after Noem’s tenure drew bipartisan scrutiny over spending, her comments about ICE‑related killings, and recent Senate testimony.”
He designated Noem as a special envoy tied to a new "Shield of the Americas" initiative.
The move made Noem the first Cabinet secretary to leave in his second term.
Multiple outlets reported that Trump announced the dismissal on social media and positioned Noem for a new role as part of the administration’s hemispheric security push, framing the change as both a personnel and policy reorientation.
Reasons for Noem's firing
The firing followed combative and widely criticised congressional hearings in which Noem’s testimony angered lawmakers and reportedly "incensed" the president. Reporters and lawmakers highlighted disputes over a controversial multi-hundred-million-dollar ad campaign, DHS spending, and Noem’s comments about killings involving immigration officers. Those exchanges, along with scrutiny of department contracts and internal conduct, were cited repeatedly as the proximate causes of her removal.
Mullin nomination and transition
Trump moved quickly to name Sen. Markwayne Mullin (R-Okla.) as his pick to replace Noem.
“He named Sen. Markwayne Mullin (R‑Okla.) as his pick to replace Noem, calling him a ‘MAGA Warrior’; Mullin would need Senate confirmation and had not yet responded publicly. Trump said Mullin would start March 31.”
Media reported that Mullin must be confirmed by the Senate but could serve as acting secretary while his nomination is pending.
Coverage flagged Mullin as a prominent contender despite controversies and gaffes noted by commentators.
The administration reportedly set an early start date for the transition.
Responses to Noem's ouster
Reactions to Noem’s ouster were split along predictable partisan lines: critics and Democratic leaders praised the move, while immigration hard-liners and some DHS officials defended her record. Noem herself publicly thanked Trump and emphasised department accomplishments, even as local and national figures highlighted the political and operational fallout of her removal. Observers tied the personnel change to larger political battles over immigration policy and DHS funding.
Leadership shift and policy fights
The leadership shift comes amid broader policy contests, including a DHS funding fight and a partial department shutdown. The change is linked to the administration’s new Shield of the Americas initiative, and officials announced plans for a summit to unveil the effort even as Noem transitions to a special‑envoy role. Coverage noted operational claims from DHS under Noem about declines in border encounters, which supporters used to defend her tenure even as critics focused on spending, contracts, and testimony.
“Trump announced the dismissal on Truth Social and said Noem will become Special Envoy for a ‘Shield of the Americas’ security initiative to be unveiled in Doral, Florida.”
