Trump Withdraws Endorsement of Lahmeyer, Supports Tedford in Oklahoma Congressional Race

President Donald Trump withdrew his endorsement of Oklahoma GOP congressional candidate Jackson Lahmeyer on June 17, 2026, and endorsed Republican rival Mark Tedford instead. This change occurred shortly before Lahmeyer announced the suspension of his campaign. Lahmeyer stated that he made the decision to end his campaign the night before and informed his wife and campaign team prior to Trump's announcement. According to AP results, Tedford received 32.2% of the vote, while Lahmeyer received 25.9%, both advancing to a runoff election to succeed Rep. Kevin Hern, who is running for the U.S. Senate. Trump had previously endorsed Lahmeyer, calling him a "MAGA Warrior." In a statement on Truth Social, Trump expressed appreciation for Lahmeyer's efforts but stated he would support Tedford, describing him as "Pro Trump and MAGA all the way." Lahmeyer announced his campaign suspension shortly after Trump's endorsement switch, citing personal considerations. The reasons for Trump's endorsement change were not publicly explained by either Trump or the White House. Tedford is now seen as the likely Republican nominee in the district.
