The Latest: Ken Paxton wins Senate primary runoff in Texas, defeats incumbent Sen. John Cornyn

Texas Attorney General Ken Paxton defeated four-term Sen. John Cornyn in a high-profile Senate primary runoff, a result buoyed by a Trump endorsement delivered last week. Paxton's victory advances him to a November contest against Democratic state Rep. James Talarico. The win underscores the influence of President Trump within the GOP as he seeks to penalize Republicans he views as disloyal. Cornyn, a former NRSC chair, had support from established party figures but could not withstand Paxton's challenge. Democrats also selected U.S. House nominees on Tuesday, with the party backing Johnny Garcia and opposing Maureen Galindo, whose past remarks drew swift condemnation from national Democrats. The slate highlights the continuing Trump-backed wave in competitive races, while Democrats warned that antisemitic rhetoric from some GOP-aligned candidates could hurt the party.
