President Donald Trump has signaled he is considering an endorsement in the Texas U.S. Senate Republican primary runoff between incumbent Sen. John Cornyn and Texas Attorney General Ken Paxton ahead of the May 26 contest, with early voting beginning May 18. Trump recently told reporters he likes both candidates and may decide “relatively soon,” following the March primary that forced the runoff after neither secured a majority. Cornyn’s May 10 social media repost of content from a group critical of Trump has drawn backlash from some Republican voters, while Paxton has positioned himself as a stronger alignment with the president’s priorities. Trump’s extensive record of primary endorsements in 2026 has already shaped numerous House and Senate races, underscoring the potential influence such a statement could carry in this closely watched contest.
