NPR reports multiple campaign events for Texas Attorney General Ken Paxton in May 2026 and notes President Trump's endorsement of Paxton against four-term Senator John Cornyn in the Republican primary, described as the most expensive in Senate history. Supporters quoted at events contrasted Paxton with Cornyn. Analyses from progressive, conservative, libertarian, and devil's advocate perspectives interpret the race differently while sharing the same NPR-sourced facts.
