President Donald Trump's anticipated endorsement remains undecided in the Texas U.S. Senate Republican primary runoff between incumbent Sen. John Cornyn and Attorney General Ken Paxton, following the March 3 primary where neither secured a majority. Trump pledged in early March to back one candidate and urge the other to withdraw, but missed a key deadline and has stayed neutral amid intense MAGA pressure against the establishment-aligned Cornyn. The May 26 runoff heightens stakes for GOP primary dynamics. Recently, Trump re-endorsed Sen. Lindsey Graham in South Carolina and shows signals of supporting Steve Hilton for California governor, with announcements tracked via Truth Social or reliable reporting through November 2026.
