A change in position for the U.S. Secretary of Homeland Security (DHS) occurred on Thursday, when President Donald Trump nominated Markwayne Mullin to replace Kristi Noem.
Noem was removed following continual congressional hearings regarding her leadership, specifically the handling of immigration crackdowns and a $220 million taxpayer-funded ad campaign that featured Noem. During the ad campaign, a policy instituted by Noem requiring her approval for any Federal Emergency Management Agency (FEMA) expenses over $100,000 delayed over 1,000 contracts, including funding for disaster relief in Los Angeles and North Carolina.
Later in the day, Trump announced he was anointing Mullin as the next Secretary of DHS. Mullin served as a Republican United States junior senator for Oklahoma since 2023. He was elected during a special election to fulfill the rest of former Senator Jim Inhofe’s term. Before that, he served five terms in the House of Representatives for Oklahoma’s 2nd Congressional District. He is a businessman, an enrolled member of the Cherokee Nation and holds an Associate of Applied Science in construction from Oklahoma State University Institute of Technology. Trump described Mullin as a “MAGA Warrior” and a supporter of his “America First” program. In the Senate, Mullin frequently voiced support for Trump’s immigration and border control policies. Mullin publicly supported DHS efforts to detain undocumented immigrants, aligning with the Trump administration’s goals to “Stop Migrant Crime” and prevent illegal drug smuggling across borders.
Mullin was among the Republicans to call the latest government shutdown a “political theater,” believing it was not about policy, but rather about politicians navigating future careers and attempting to influence elections.
As an enrolled member of the Cherokee Nation, Mullin is expected to provide a better understanding of federal Indian policy and law within the agency, addressing recent controversies surrounding Immigration and Customs Enforcement (ICE) actions against tribal members.
He is set to take the position on Mar. 31 as acting secretary while his confirmation process unfolds. His appointment as secretary is poised to escalate tensions between the federal government and California, particularly in immigration enforcement and border security. Following Trump’s announcement to appoint Mullin, California Governor Gavin Newsom called the secretary candidate an “erratic, unstable man,” citing concerns over his and the Trump administration’s approach to immigration.
