SAN ANTONIO – Texas Attorney General Ken Paxton has announced a new lawsuit after a swimming competition allegedly allowed for transgender athletes to compete.

Ken Paxton filed the lawsuit against U.S. Masters Swimming (USMS) after having launched an investigation into the body, which determined the organization had “engaged in false, deceptive, and misleading practices by allowing men to compete in women’s events.”

We were unable to independently confirm if any swimmers participating in the women’s category were either men or transgender women.

According to U.S. Masters Swimming, the organization is a recreational swimming organization for adults 25 and older, emphasizing participation and enjoyment. The organization does not offer financial rewards to winning participants.

“U.S. Masters Swimming’s insane policy of allowing men to participate in women’s competitions is both deeply unfair to female competitors and unlawful,” said Attorney General Paxton. “The organization has cowered to radical activists pushing gender warfare, and it has deprived female participants of the opportunity to succeed at the highest levels by letting men win countless events. This lawsuit will hold USMS accountable for its actions, and we will continue to fight to protect the integrity of women’s sports.”

The investigation stems from an accusation that U.S. Masters Swimming allowed men to compete against women during the 2025 Spring Nationals swim meet in San Antonio.

According to Ken Paxton’s website, the lawsuit highlights USMS’s “false, deceptive, and misleading practices,” of saying that their women’s events would only be available for those assigned female at birth, “only to turn around and steal awards and recognitions for women by giving them to men competing in women’s events.”

We were unable to independently confirm if any swimmers participating in the women’s category were men, transgender women, or transgender men.
