One day before the office of Texas attorney general Ken Paxton released a letter threatening legal action against the Big 12 conference if it moved to sanction Texas Tech over quarterback Brendan Sorsby’s eligibility saga, Texas Tech board of regents chair and billionaire booster Cody Campbell donated $274,300 in support of Paxton’s U.S. Senate campaign.According to a recent batch of campaign finance records filed to the Federal Election Committee, Campbell made the donation on June 10 to Paxton Victory, a joint fundraising committee for Paxton’s ongoing run for Senate as the Texas Republican nominee. On June 11, Paxton’s attorney general office sent a formal letter to the Big 12 Conference on behalf of Texas Tech University stating any penalties imposed by the Big 12 regarding Sorsby would be considered “unlawful” and met with legal action.Under Texas state law, the attorney general represents Texas Tech University in court and legal proceedings, and the university’s general counsel interacts with the attorney general’s office.Campbell declined to comment on the matter. The Texas attorney general office and Paxton’s Senate campaign did not immediately respond to requests for comment. Texas Tech did not immediately respond to a request for comment.The Texas Tribune first reported the news of Campbell’s donation on Wednesday night. Additional campaign finance records show that Campbell regularly donates to Republican politics nationally and in Texas. This includes multiple donations to Wesley Hunt and his campaign for the same U.S. Senate seat, as well as to incumbent Texas senator John Cornyn; Hunt and Cornyn were Paxton’s opponents in the Republican primary race, which Paxton won in March.Campbell made prior donations to Paxton’s Senate campaign dating back to 2025 and to Paxton in his capacity as attorney general. The June 10 donation to Paxton’s Senate campaign represents Campbell’s largest one-time amount given toward a state-level politician dating back to 2016, according to campaign finance databases.
