Texas Attorney General Ken Paxton announced Tuesday that he’s running to unseat Senator John Cornyn in next year’s Republican primary, extending a lengthy feud between the two men.

In a Senate hearing, the Texas Republican pushed back on concerns over the sharp decline in global financial markets that the tariffs have set off.

Texas’s two U.S. senators admit that the economic fallout from the Trump administration’s tariffs could have an impact on the 2026 midterm elections.

Republicans are growing anxious about an emerging Texas primary engulfing one of their longest-serving senators, fearful that a hugely expensive intraparty feud will have major ramifications across the map in next year’s midterms.

Republican Sen. John Cornyn's early campaign efforts have been targeted at the GOP's most conservative voters.
