Sen. John Cornyn raised $7 million during the fourth quarter of his reelection campaign — the highest total of his career as the Republican fights a bitter primary challenge.

The fundraising report, shared first with Blue Light News, shows Cornyn has more than $15 million in cash on hand, including money raised through his two joint fundraising committees. It represents more than twice as much as he raised in the third quarter of 2025.

The four-term incumbent is up against Texas Attorney General Ken Paxton and Rep. Wesley Hunt. Polls show a tight race between Paxton and Cornyn, with Hunt in third, ahead of the early March primary.

Cornyn has poured money into attacking Paxton, a conservative firebrand who has wide backing from the MAGA base in Texas but has significant political and personal baggage. Paxton has faced multiple state and federal investigations and his wife filed for divorce last summer.

“Texans understand that President Trump’s legislative agenda and the Senate Republican majority are at risk unless Sen. Cornyn is the nominee,” said Andy Hemming, Cornyn’s campaign manager, in a statement. “We are executing our plan to win this race, and we will win.”

Paxton and Hunt have not yet released their own latest fundraising hauls. The race is expected to go to a runoff in late May.
