Lawmakers question the Oklahoma senator’s readiness to lead Homeland Security as immigration policy and agency operations remain under scrutiny.

Sen. Markwayne Mullin appeared before the Senate on Wednesday for his confirmation hearing as President Donald Trump’s nominee to lead the Department of Homeland Security, facing questions over his plans to oversee a department central to the administration’s immigration and national security agenda.

Mullin, a Republican from Oklahoma and longtime ally of the president, has served in Congress for 13 years. If confirmed, he would succeed former Secretary Kristi Noem, who was removed from the position earlier this month following criticism tied to her leadership of the agency.
The hearing marks the first time Mullin has publicly outlined his approach to managing the department, which employs approximately 260,000 personnel and is responsible for a wide range of operations, including presidential protection, disaster response, and immigration enforcement.
Before entering politics, Mullin operated a plumbing business and competed as a mixed martial arts fighter. During his time in Congress, he has expressed support for immigration enforcement measures and is expected to align closely with Trump’s policy priorities.
“Whether it be protecting the homeland from bad actors, stopping dangerous drugs from flowing into American communities, or removing the worst-of-the-worst criminal illegal aliens, Senator Mullin will work tirelessly to implement the President’s agenda,” White House spokeswoman Abigail Jackson said in a statement.
Immigration enforcement is expected to remain a central focus of the confirmation process, particularly as the administration’s deportation strategy faces political and operational challenges. Democrats have pressed for changes to enforcement practices and have withheld support for DHS funding amid concerns over officer conduct.
Sen. Gary Peters of Michigan, the ranking Democrat on the Senate Homeland Security and Governmental Affairs Committee, said in prepared remarks that lawmakers are seeking “straightforward” reforms comparable to standards followed by police departments. He also cited broader threats facing the department, including those tied to Iran and cyberattacks, and said DHS requires leadership with a “steady hand,” while expressing “reservations” about Mullin’s qualifications.
The hearing takes place during an ongoing partial government shutdown affecting DHS operations. Reports of extended security lines at airports have emerged as Transportation Security Administration screeners continue working without pay. Republican lawmakers have argued that the funding impasse poses risks to national security, while Democrats maintain that reforms to enforcement practices are necessary before funding is restored.
During Noem’s tenure, DHS carried out large-scale immigration enforcement actions in cities including Los Angeles, Chicago, and Minneapolis. Those operations included arrest sweeps that led to confrontations between federal officers and demonstrators. Critics, including activists and some elected officials, accused DHS personnel of using excessive force and detaining individuals in poor conditions.
Two protest-related fatalities in Minneapolis—identified as Renee Good and Alex Pretti—added to public scrutiny surrounding enforcement tactics.
DHS officials have defended their operations, stating that force is used only when required and attributing escalating tensions to rhetoric from activists and political leaders.
Mullin is also expected to address questions regarding the future of the Federal Emergency Management Agency, which remains without a permanent administrator following the departure of two acting leaders during Noem’s tenure. A review council established under Noem had been tasked with proposing changes to federal disaster response, including potential reductions in federal involvement and increased responsibility for state and local governments.
Administrative procedures introduced under Noem requiring approval for contracts exceeding $100,000 contributed to delays in reimbursements to states for disaster-related expenses, according to officials familiar with the process.
Following her departure, Trump appointed Noem as a special envoy for a new Western Hemisphere-focused security initiative. In remarks after the announcement, Noem cited “historic accomplishments” during her time at DHS and said her work had strengthened national security.
Mullin’s confirmation hearing is expected to continue with additional testimony and questioning from senators as the department’s funding status and policy direction remain unresolved.
