Texas Attorney General Ken Paxton has initiated an investigation into U.S. Masters Swimming regarding potential violations of state law. This investigation comes after reports highlighting that the organization allowed transgender athletes—specifically biological males—to compete in women’s events.
The 2025 Spring National Championship took place at the Northside ISD Swimming Center in San Antonio from April 24-27.
Ana Caldas, a biological man previously known as Hugo, excelled in the championship by winning each individual medley event, including the 50 and 100 yards breaststroke, as well as the 50 and 100 yards freestyle.
As a consequence of these developments, U.S. Masters Swimming is now facing scrutiny from Paxton.
Paxton remarked, “The US Masters Swimming policy permitting men to compete in women’s events is troubling and could contravene the Texas Consumer Protection Act. This policy not only undermines female athletes but also represents a significant disregard for women, potentially violating Texas law. I am unwavering in my commitment to challenge these unfair practices and protect the integrity of women’s sports.”
In his review, Paxton intends to assess documents associated with U.S. Masters Swimming to uncover any involvement in “false, deceptive, and misleading practices.”
Ken Paxton has positioned himself as an advocate for female athletes.
