Senate Confirms Markwayne Mullin as DHS Secretary 54-45, Replacing Noem as Department Faces 38-Day Shutdown

The Senate confirmed Sen. Markwayne Mullin of Oklahoma as Secretary of Homeland Security on Monday in a 54-45 vote, handing President Trump a new leader for a department that has been embroiled in a months-long funding shutdown and a bitter dispute over immigration enforcement priorities. Mullin replaces Kristi Noem, who drew criticism from both parties over her management of the department and her use of taxpayer-funded travel before stepping down earlier this month at Trump's request.

The confirmation vote broke almost entirely along party lines, with two notable exceptions in each direction. Democratic Senators John Fetterman of Pennsylvania and Martin Heinrich of New Mexico crossed over to vote in favor of Mullin's confirmation, providing the votes that pushed the total comfortably above the 51 needed for a simple majority. On the Republican side, Sen. Rand Paul of Kentucky — who clashed sharply with Mullin during his confirmation hearing, at one point challenging the nominee to a fight — was the only member of the GOP caucus to vote no. Mullin, a former professional MMA fighter and four-term congressman before winning his Senate seat in 2022, had previously served on the Senate Armed Services and Energy committees.

Mullin inherits a department operating under severe strain. The DHS has been in a partial shutdown since February 13, when Congress failed to pass a funding bill after President Trump conditioned his support on passage of the SAVE America Act — legislation that would require proof of citizenship to register to vote and photo identification to cast ballots. Democrats have blocked the bill, calling it a voter suppression measure; Trump has instructed Republican senators to refuse any deal that does not include the elections provisions. The result has been 38 days of funding limbo that has left TSA officers working without pay, caused staffing shortages and extended security lines at major airports, and prompted the administration to deploy ICE agents to airports to supplement the depleted TSA workforce.

Speaking on the Senate floor shortly before the vote, Majority Leader John Thune said Mullin's confirmation would "give the department the strong leadership it needs at a critical moment." Senate Minority Leader Chuck Schumer countered that Mullin was "inheriting a crisis of the president's own making" and called the confirmation "a band-aid on a bullet wound" as long as the shutdown continued. Mullin said in a statement after the vote that he was "humbled and honored" to take on the role and pledged to "restore order and security at our borders and in our airports." He is expected to be sworn in Tuesday.

The confirmation comes as airport chaos driven by the TSA staffing crisis has become a flashpoint in the shutdown fight. The administration's decision to deploy ICE agents — officers trained for immigration enforcement, not aviation security — to assist at airports drew immediate protests from Democratic lawmakers, who called it both ineffective and an attempt to blend immigration politics with airport operations. Airlines have reported dramatically longer security wait times at major hubs including JFK, O'Hare, and LAX. Mullin's first days in office will be consumed almost entirely by the funding standoff: whether he can find a deal that satisfies the White House's demands for the SAVE America Act while attracting Democratic support will likely define his tenure.
