On May 29, 2026, Texas Senator John Cornyn (R-TX) lost the Republican primary to Attorney General Ken Paxton, WHO ran with President Donald J. Trump's endorsement. Cornyn, a longtime senator and former Senate GOP whip, conceded after Paxton consolidated conservative support despite Cornyn's establishment backing. Paxton's victory amplifies Trump's influence over Republican primaries in a top-tier Senate race and increases the likelihood of a more polarized general election matchup in Texas.
