Trump Ousts DHS Secretary Noem, Nominates Sen. Mullin Amid Florida Border Woes

President Trump fired Homeland Security Secretary Kristi Noem on Wednesday in the first Cabinet shakeup of his second term, nominating Sen. Markwayne Mullin (R-Okla.) to lead the department overseeing the nation's immigration enforcement and disaster response.

Noem had faced mounting bipartisan criticism on three fronts: the handling of ICE immigration enforcement operations in American cities, delays in emergency response, and a $220 million taxpayer-funded advertising campaign in which she was prominently featured. The breaking point came during Senate testimony this week when Sen. John Kennedy (R-La.) pressed Noem on whether the president had authorized the ad campaign, according to PBS NewsHour correspondent Lisa Desjardins. Noem testified that Trump had approved it; Kennedy said he spoke with Trump that night and that the president not only denied it but was "sharply angry." Noem continued with a previously scheduled speech in Nashville following her dismissal, making no mention of her firing. Trump announced she will take on a newly created role as special envoy for the Shield of the Americas.

For Treasure Coast residents, DHS leadership carries direct consequences. FEMA — the agency responsible for disaster declarations and recovery funding — falls under DHS authority. Martin, St. Lucie, and Indian River counties remain in federally designated hurricane-risk zones, and any disruption in DHS leadership during the Atlantic hurricane season could affect federal preparedness coordination along the coast.

Mullin, a lifelong Oklahoman and member of the Cherokee Nation who was elected to the House in 2012 and the Senate in 2022, said he learned of his nomination moments before Trump announced it publicly. "It was a little bit of a surprise for us," Mullin told reporters, adding he had not yet called Secretary Noem or his wife. Mullin currently serves on the Senate Armed Services and Appropriations committees but has no publicly identified homeland security background. He said last month on a conservative radio program that he is open to some form of legal status for DACA recipients and undocumented individuals who arrived more than 10 years ago — a position that could draw scrutiny during confirmation hearings. Democratic Sen. John Fetterman of Pennsylvania has already indicated he will vote yes.

A confirmation vote date has not been announced. Republicans hold 53 Senate seats, requiring only 50 votes for Cabinet confirmation.
