Markwayne Mullin's confirmation hearing before the Senate Homeland Security Committee on March 18, 2026, was defined by a sharp personal confrontation with Sen. Rand Paul of Kentucky. Paul, referencing Mullin's widely reported comments from 2023 in which the former Oklahoma senator expressed understanding for why Paul's neighbor attacked him — an assault that left Paul with six broken ribs — questioned whether Mullin possessed the temperament to lead the nation's largest law enforcement agency. Mullin attempted to dismiss the exchange as "old news," but Paul pressed him repeatedly, calling the comments "an endorsement of political violence."
Beyond the theatrics, the hearing produced a substantive policy development that surprised observers on both sides of the immigration debate. Mullin stated under oath that, if confirmed, he would require ICE agents to obtain judicial warrants before entering private homes to make arrests — a significant departure from the policy under his predecessor Kristi Noem, who had authorized ICE to conduct home raids using only administrative warrants signed by ICE supervisors rather than judges.
The warrant commitment drew immediate praise from immigrant rights organizations, who noted that administrative warrants lack the Fourth Amendment protections of judicial warrants, including the requirement of probable cause reviewed by a neutral magistrate. However, immigration hawks within the Republican caucus expressed concern that the policy shift would slow enforcement operations. Tom Homan, who had been operating as de facto immigration enforcer, was notably silent on the commitment.
The hearing lasted more than five hours and covered a range of DHS responsibilities beyond immigration, including cybersecurity, the ongoing DHS funding lapse, and FEMA disaster preparedness. Mullin repeatedly emphasized his intention to "restore professionalism" to the department, a phrase widely interpreted as an implicit critique of Noem's turbulent tenure.
