Senate Confirms Markwayne Mullin as DHS Secretary as Bipartisan Shutdown Deal Takes Shape

The Senate confirmed former Oklahoma Sen. Markwayne Mullin as the next Secretary of Homeland Security on Monday, the chamber's 39th day of a partial government shutdown at DHS, as bipartisan negotiators simultaneously edged toward a deal that could finally reopen the embattled department and put hundreds of thousands of federal workers back on the payroll.

The confirmation vote, which passed on a mostly party-line basis, ended weeks of delay tied directly to the ongoing funding impasse. Republicans had argued that confirming a permanent secretary was essential to breaking the stalemate, while Democrats insisted that leadership clarity could not substitute for a comprehensive funding agreement that would also address their demands for reforms to Immigration and Customs Enforcement. Mullin, 47, a former mixed martial arts fighter turned Republican congressman who later served as an Oklahoma senator, was nominated by President Donald Trump in late February to lead the department overseeing the Transportation Security Administration, Border Patrol, ICE, the Coast Guard, FEMA, and the Secret Service.

He will take the helm of a department that has been partially shuttered since February 14, when Democrats blocked passage of a government funding bill they said failed to impose adequate constraints on immigration enforcement operations following two fatal shootings of civilians by federal agents in Minneapolis in January. At a swearing-in ceremony hosted by President Trump at the White House Monday afternoon, Trump praised Mullin as a 'fighter' uniquely suited to the agency's mission, saying the new secretary would 'restore law, order, and full function' to the department. Mullin pledged to work with Congress to resolve the funding dispute 'in the interests of the American people' and called on senators to pass a bill that would return TSA workers to the paycheck and restore airport security staffing to normal levels.

The shutdown has taken a significant toll on the traveling public and on federal workers. More than 400 TSA officers have resigned since the shutdown began, and unscheduled absences at checkpoints have doubled, triggering wait times of up to 120 minutes at major hubs including Houston Intercontinental Airport and Atlanta Hartsfield-Jackson. ICE agents have been deployed as a stopgap to 14 airports experiencing the worst delays — a legally improvised measure condemned by Democrats as an inappropriate use of immigration enforcement personnel in a domestic transportation security role. Airlines have reported hundreds of millions of dollars in rebooking costs as travelers have increasingly rescheduled travel to avoid peak-period chaos.

Behind the scenes, White House border czar Tom Homan spent a second consecutive day meeting Monday with a bipartisan group of senators — including Republican Sens. Katie Britt, Bernie Moreno, Lindsey Graham, and Steve Daines — on a framework that would fund most DHS agencies while temporarily setting aside the ICE enforcement budget. That funding would later be pushed through budget reconciliation along with the SAVE America Act, Trump's voter-ID legislation. Key Democrats emerged cautiously optimistic. 'We do have a solution,' Sen. Britt told reporters after the White House session. Sen. Susan Collins said she was 'more optimistic that by the end of the week we will fund the Department of Homeland Security.' Mullin's first full day in office begins Tuesday, with immediate briefings on shutdown status, personnel attrition, and the security implications of the ongoing Iran conflict for domestic aviation.
