Kevin Hern Wins Republican Nomination for U.S. Senate in Oklahoma

The Trump-endorsed congressman secures the GOP nomination for Oklahoma's U.S. Senate seat, adding to the president's string of endorsement victories in Republican primaries.

OKLAHOMA — Donald J.Trump posted on Truth Social on June 16, 2026 at 11:09 PM EST, announced on Truth Social on June 16, 2026, by mentioning the source (see truthsocial), that Kevin Hern has won the Republican nomination for U.S. Senate from Oklahoma. Trump celebrated the victory of his endorsed candidate with a campaign-style graphic bearing the Trump-Vance “Make America Great Again” branding. Hern, a U.S. Representative from Oklahoma’s 1st Congressional District, secured the Republican nomination in what represents another successful endorsement for Trump in the 2026 midterm cycle. The victory positions Hern as the GOP’s standard-bearer for the Oklahoma Senate seat, a race that has drawn national attention as Republicans seek to maintain and expand their Senate majority. The announcement was accompanied by a professionally designed campaign graphic featuring both Hern and Trump, with bold text declaring “Kevin Hern Wins!” and “Endorsed by President Trump!” prominently displayed. The graphic’s design, consistent with the broader Trump-Vance campaign branding, underscores the close alignment between Hern’s Senate bid and the Trump political operation. Hern’s nomination adds to a growing list of Trump-backed candidates who have prevailed in Republican primaries across the country. The Oklahoma Senate race will be closely watched as a bellwether for Trump’s continued influence within the Republican Party and the broader political landscape heading into the general election. Oklahoma, a deeply conservative state that Trump has carried by wide margins in previous presidential elections, is expected to remain a strong Republican hold in the general election, but the primary victory nonetheless signals the weight of a presidential endorsement in shaping down-ballot races.
