President Trump endorsed Rep. Kevin Hern for the U.S. Senate on Friday night, moving fast to shape the Oklahoma race before a crowded field can form.
The endorsement landed just two days after Hern launched his campaign, and one day after Trump met with Gov. Kevin Stitt in Washington to discuss the coming vacancy. The seat opens when Sen. Markwayne Mullin, one of Trump's closest allies, leaves to lead the Department of Homeland Security.
Trump made his pick clear on Truth Social, as The Oklahoman reported:
"Kevin Hern will be an outstanding Senator, and has my Complete and Total Endorsement, HE WILL NEVER LET YOU DOWN!"
Trump praised Hern for doing a "tremendous job" in the House advancing the administration's agenda and said he expected the same in the Senate. His post also noted he won all 77 Oklahoma counties in the past three presidential elections, a reminder that his word carries serious weight in this deep-red state.
The endorsement could clear the field before it fills. Both Stitt and U.S. Rep. Stephanie Bice already announced they would not seek the seat.
As the Washington Examiner noted, Bice had been considering a run, while Hern was seen as a candidate who could pour significant personal funding into a campaign. That financial muscle is real. Federal Election Commission records show Hern reported $2.2 million in cash in his campaign account as of December. Investment research site Quiver Quantitative estimated his net worth at $110 million, a fortune built operating McDonald's franchises.
Hern has represented parts of eastern Oklahoma in the U.S. House since 2018. He held a news conference at state GOP headquarters in Oklahoma City on Thursday to launch his campaign, touting his close ties with Trump and a voting record aligned with the president's priorities.
When asked at that event whether Trump was backing his race, Hern would not say. He didn't have to wait long for the answer.
Trump announced on March 5 that he was tapping Mullin to lead DHS, a move that followed Kristi Noem's reassignment from the department to a new Western Hemisphere envoy role. Most Americans backed that leadership change, and Mullin's nomination signals Trump wants a proven ally running border security.
Once the Senate confirms Mullin, Stitt must appoint someone to fill the remaining months of the current term. Under Oklahoma law, that appointee cannot run in the subsequent election for the full term. Voters will pick a permanent replacement in November.
Stitt said after his March 12 meeting with Trump that he would wait to name his pick until Mullin's confirmation clears the Senate. Political insiders believe oil magnate and Trump megadonor Harold Hamm and communications executive Dustin Hilliary, one of Stitt's advisers, sit on the governor's short list for the interim appointment.
Oklahoma Sen. James Lankford captured the pace of what's coming. He told the Washington Examiner:
"There'll be a gaggle of folks, I'm sure, that will jump in for a exceptionally fast race that's about to happen."
That prediction may need revising. Trump's early endorsement sends a blunt signal to would-be challengers: the president has made his choice. In a state he swept county by county, that signal carries the force of a closing door.
Republicans hold a narrow Senate majority. Every seat counts. Losing a safe red seat to a messy primary or a weak nominee would be a self-inflicted wound, the kind of mistake the GOP has made before. Trump's swift endorsement aims to prevent exactly that, consolidating conservative support behind a tested House member with deep pockets and a proven record.
The confirmation fight over Mullin's DHS appointment will test Senate unity, much like recent clashes over Trump staffing decisions. But in Oklahoma, the political math is simpler: Trump dominates, and his endorsement is the single most valuable asset in any Republican primary.
Key facts at a glance:
When the president of the United States picks your candidate two days into the race, the primary is less a contest and more a formality. That's how you hold a seat, and hold a majority.
