The U.S. Senate’s Homeland Security & Governmental Affairs Committee will hold a confirmation hearing on March 18 for Markwayne Mullin, President Donald Trump’s nominee to lead the U.S. Department of Homeland Security (DHS).
The hearing will take place at 9:30 a.m. in the Dirksen Senate Office Building before the Senate Committee on Homeland Security and Governmental Affairs.
Mullin, a Republican senator from Oklahoma and a citizen of the Cherokee Nation, was nominated on March 5 following the abrupt removal of DHS Secretary Kristi Noem. Trump announced the leadership change after a series of controversies surrounding the department and mounting criticism of Noem’s tenure.
If confirmed, Mullin would take over one of the federal government’s largest and most complex agencies, responsible for immigration enforcement, border security, disaster response, cybersecurity, and domestic counterterrorism.
Scrutiny Expected at Hearing
The confirmation hearing is expected to draw intense questioning from both parties as lawmakers examine Mullin’s qualifications, policy positions, and past controversies.
One point of attention may come from fellow Republican Sen. Rand Paul, who chairs the committee overseeing the nomination. The two lawmakers have publicly clashed in recent months, raising the possibility of a tense exchange during the hearing.
Mullin could also face questions about his business background. Reports resurfaced this week about a past controversy involving his family plumbing company and a former employee who illegally stored firearms at the workplace, an issue critics say raises questions about oversight and judgment. Mullin has denied knowingly violating any law.
A Historic Nominee
Mullin is among the few Native Americans to serve in the U.S. Senate and the first Native senator since 2005. Before his election to the Senate in 2022, he served five terms in the U.S. House of Representatives representing Oklahoma’s 2nd Congressional District.
His nomination also reflects the Trump administration’s effort to reinforce its immigration and border security agenda, which remains a central focus of DHS operations.
What Happens Next
Following the March 18 hearing, the Senate Homeland Security and Governmental Affairs Committee must vote on whether to advance Mullin’s nomination to the full Senate. If approved by the committee, the entire Senate will then vote on final confirmation.
If confirmed, Mullin would assume leadership of DHS as the agency continues to face political pressure over immigration enforcement, border security policy, and internal management challenges.
