Trump withdraws endorsement of Oklahoma GOP candidate Jackson Lahmeyer after he suspends campaign, backs Mark Tedford instead

President Donald Trump has withdrawn his endorsement of Oklahoma Republican congressional candidate and pastor Jackson Lahmeyer and instead backed rival Mark Tedford, Fox News reported on June 17, after Lahmeyer suspended his campaign. The developments mark a rapid change in the line of support from Trump as the race moves through the late stages of the 2026 midterm cycle.

According to the Fox report, Lahmeyer had previously received Trump’s endorsement, but Lahmeyer’s subsequent decision to suspend his campaign prompted Trump to withdraw that endorsement. The report said Trump then directed support toward Tedford, shifting the focus of the president’s stated backing within the same Oklahoma contest.

The underlying race is described by Fox News as an Oklahoma GOP congressional contest between Lahmeyer and Tedford. Beyond the names of the candidates and their roles in the contest, the report did not provide additional confirmed details in the materials provided here, including vote counts, primary results, filing status, or whether Tedford would face any formal changes to ballot access.

A presidential endorsement is political, not legal. It does not by itself determine who is certified on the ballot or how elections are administered. In practice, however, endorsements can affect candidate fundraising, volunteer recruitment, and the pace of national messaging, particularly when paired with a candidate suspending a campaign and stepping out of active voter outreach.

Lahmeyer’s suspension, as described by Fox News, effectively removes him as an active campaign contender. That shift can alter how party operatives and donors coordinate resources in the district, and it can also leave supporters of the previously endorsed candidate seeking an alternative aligned with the remaining field.

Trump’s endorsement change to Tedford means the president’s public political backing is now directed at a different candidate in the same Oklahoma congressional race. While that does not change the legal requirements for campaigning or voting, it can influence which candidate receives national attention and which campaign organizations benefit from heightened visibility.

The next steps depend on state election procedures and the exact status of Lahmeyer’s candidacy at the time of suspension. Those details, including whether any withdrawal affects ballot listings or triggers replacement rules, were not provided in the materials here and would require confirmation from Oklahoma election records or official filings.

It remained unclear from the information provided here whether Tedford would treat Trump’s endorsement as an immediate boost to campaign operations, whether Lahmeyer’s suspension includes withdrawal from ballot access, or whether any litigation or administrative filings followed the suspension. Those questions are likely to be resolved through subsequent reporting and election-official documentation.
