In a swift move that has shaken the nation’s capital, President Donald Trump announced on Thursday that Kristi Noem will be leaving her post as Secretary of the Department of Homeland Security. In her place, the President has tapped Oklahoma’s junior Senator, Markwayne Mullin, to lead the agency and oversee his administration’s mass deportation agenda.
The shakeup comes after weeks of intensifying friction between Noem and both sides of the aisle in Congress. Tensions reached a breaking point this week following Noem’s testimony before the House and Senate Judiciary committees. President Trump was reportedly “furious” after Noem claimed during a heated exchange with Sen. John Kennedy that the President had personally approved a controversial $220 million taxpayer-funded ad campaign featuring her.
A Bond Forged in Crisis
Senator Mullin’s ascent to the Cabinet marks the latest chapter in a deeply personal relationship with the President. While many allies have built their ties through politics, Mullin and Trump share a bond that began in 2020 following a family tragedy.
After Mullin’s son, Jim, suffered a life-threatening head injury during a wrestling match, Trump reportedly called the family every week during the 18-month rehabilitation process. This personal connection evolved into a political partnership, with Mullin becoming one of the President’s most reliable “fighters” in the Senate.
As a former MMA fighter and a citizen of the Cherokee Nation, Mullin has utilized his background to serve as a high-profile surrogate for the administration’s policies. Often referred to as “The Connector,” Mullin has been instrumental in bridging the gap between the White House and the House Republican majority to advance the President’s legislative priorities.
The Future of Oklahoma’s Senate Seat
Mullin’s transition to the Department of Homeland Security creates an immediate vacancy in the U.S. Senate. Under Oklahoma law, the responsibility to fill this seat falls to Governor Kevin Stitt.
Mullin had previously been seeking his first full six-year term in the upcoming 2026 election. His departure leaves a “Solid Republican” seat open for a new wave of contenders, with names like Congressman Kevin Hern and Attorney General Gentner Drummond often mentioned in political circles, though both are currently pursuing other offices.
According to Governor Stitt’s office, the Governor will be making an Appointment to fill out the remainder of the Mullin seat, which runs through January 2027. The unknown is who will decide to file for the US Senate seat that Senator Mullin would have been the heavy favorite to retain this November. Candidate filing begins in early April and the political landscape in Oklahoma has just been rocked by a 7.0 earthquake.
