WASHINGTON — The Senate Homeland Security and Governmental Affairs Committee is expected to vote Thursday morning on President Donald Trump's nomination of Sen. Markwayne Mullin to lead the Department of Homeland Security, following a confirmation hearing on Wednesday that produced sharp exchanges over the nominee's temperament, immigration enforcement policy, and unverified claims about overseas military experience Trump DHS pick Markwayne Mullin will appear before senators for his confirmation hearingapnews.com·SecondaryMarkwayne Mullin faced questions Wednesday from the Senate Homeland Security and Governmental Affairs Committee.

Mullin, a Republican from Oklahoma and former mixed martial arts fighter, would replace Kristi Noem, who was fired earlier this month amid mounting criticism of her leadership at the department. If confirmed, he would inherit an agency at the center of the administration's immigration enforcement agenda — and one currently operating without routine funding as Senate Democrats withhold appropriations in a standoff over how immigration officers conduct operations Trump DHS pick Markwayne Mullin will appear before senators for his confirmation hearingapnews.com·SecondaryMarkwayne Mullin faced questions Wednesday from the Senate Homeland Security and Governmental Affairs Committee.

A Hearing That Started With a Fight

The confirmation hearing opened with an unusually confrontational exchange between Mullin and the committee's own chairman, Sen. Rand Paul of Kentucky. Paul pointed to comments Mullin had made after a funding dispute earlier this year, when the Oklahoma senator reportedly called Paul a "freaking snake" and suggested he understood why a neighbor had physically attacked Paul in 2017 — an incident that left Paul with multiple broken ribs Trump DHS pick Markwayne Mullin will appear before senators for his confirmation hearingapnews.com·SecondaryMarkwayne Mullin faced questions Wednesday from the Senate Homeland Security and Governmental Affairs Committee.

Paul questioned whether someone who had appeared to condone violence against a political opponent was suited to lead an agency that had faced sustained criticism over its use of force. Mullin did not apologize.

Paul told reporters after the hearing that he would not vote for Mullin's confirmation. With Republicans holding an 8-to-7 majority on the committee, Paul's opposition means Mullin would need at least one Democratic vote to advance. Sen.

Markwayne Mullin, the nominee to lead the Department of Homeland Security, said he would require judicial warrants for federal immigration agents to enter private homes or businesses, signaling a potential policy shift from his predecessor Kristi Noem.

Policy Signals: Warrants, FEMA, and Enforcement

Beyond the fireworks with Paul, the hearing produced several notable policy commitments from Mullin. He told the committee that under his leadership, federal immigration officers would require a warrant signed by a judge before forcibly entering a home or business to make an arrest — a potential departure from the approach under Noem, when officers relied on administrative warrants that critics argued circumvented constitutional protections Trump DHS pick Markwayne Mullin will appear before senators for his confirmation hearingapnews.com·SecondaryMarkwayne Mullin faced questions Wednesday from the Senate Homeland Security and Governmental Affairs Committee.

Mullin also said he would not send DHS law enforcement to polling places for the purposes of voter intimidation, responding to concerns that followed Trump's call last month to nationalize elections.

On the Federal Emergency Management Agency, Mullin said he would seek to restructure FEMA rather than abolish it — a notable distinction given that Trump has publicly floated eliminating the agency altogether.

The Pretti Retraction

One of the hearing's most closely watched moments came when Mullin addressed his earlier comments about Alex Pretti, a Minneapolis ICU nurse and federal employee who was shot and killed by immigration enforcement officers earlier this year. In the immediate aftermath of the shooting, Mullin had publicly described Pretti as a deranged individual — echoing language used by Noem before any investigation had been completed Trump DHS pick Markwayne Mullin will appear before senators for his confirmation hearingapnews.com·SecondaryMarkwayne Mullin faced questions Wednesday from the Senate Homeland Security and Governmental Affairs Committee.

Mullin acknowledged on Wednesday that the characterization had been premature. He told the committee he should not have made the remark and that as secretary he would exercise more restraint before commenting on active investigations.

Questions Over a Classified Trip

Sen. Gary Peters of Michigan, the top Democrat on the committee, pressed Mullin on statements he had made on Fox News about having firsthand experience of war.

When Peters asked for specifics, Mullin said he had participated in an official overseas trip in 2015 while serving in the House, one that required specialized training qualifications. He repeatedly described the details as classified and declined to elaborate.

Bipartisan Support, Within Limits

Despite the friction with Paul and sustained Democratic criticism of the administration's immigration policies, Mullin entered the hearing with a visible show of bipartisan backing. He was flanked by former House Speaker Kevin McCarthy, a Republican, and Rep. Josh Gottheimer, a moderate Democrat from New Jersey. Seated directly behind him was Teamsters President Sean O'Brien, the union leader with whom Mullin had nearly come to physical blows during a 2023 Senate hearing — and with whom he has since become friends DHS nominee Markwayne Mullin gets Senate hearing Wednesdaycnbc.com·SecondarySen.

What Comes Next

If the committee approves Mullin's nomination on Thursday, the full Senate could take up the confirmation vote as early as next week, ahead of a scheduled two-week recess. The timing underscores the urgency with which the administration is seeking to install permanent leadership at a department that has been without a confirmed secretary since Noem's dismissal — and which continues to operate under a partial government shutdown that has left TSA screeners and other essential personnel working without pay for weeks Trump DHS pick Markwayne Mullin will appear before senators for his confirmation hearingapnews.com·SecondaryMarkwayne Mullin faced questions Wednesday from the Senate Homeland Security and Governmental Affairs Committee.

The outcome of Thursday's vote will hinge on whether Fetterman's stated support holds and whether any additional Democrats or Republican holdouts emerge. For Mullin, the path from a contentious hearing to a committee vote in less than 24 hours reflects both the political pressure to fill the vacancy and the unusual dynamics of a nomination where the biggest obstacle came from within the nominee's own party.
