Texas Attorney General Ken Paxton’s office is launching an investigation into possible violations of state law by U.S. Masters Swimming.

In a press release issued Monday, the office said it would review documents related to reports that the organization allowed a biological male to compete in a women’s swimming event in San Antonio.

The probe will specifically focus on whether U.S. Masters Swimming engaged in false, deceptive, and misleading acts and practices by marketing the event as a women’s sporting event but allowing men to compete.

“The policy of US Masters Swimming, which allows men to compete in women’s events, is reprehensible and could violate Texas’s consumer protection laws,” stated Paxton.

“Not only is this policy insulting to female athletes, but it also demonstrates deep contempt for women and may violate Texas law,” he continued. “I will fight to stop these unfair policies and never back down from defending the integrity of women’s sports.”

Citizens first sounded the alarm after Hugo “Ana” Caldas, a 47-year-old male who identifies as a female, took first place in five events at the 2025 Spring Nationals, held at the Northside Independent School District Swim Center in late April.

Caldas specifically got first place in the 50-yard breaststroke, 100-yard breaststroke, 50-yard freestyle, 100-yard freestyle, and 100-yard individual medley in the 45-49 category.

His 50-yard breaststroke was won by “a full 3 seconds, in a time of 29.74,” posted women’s sports activist Beth Bourne on X. “Anyone who competes in swimming at the national level knows this is unheard of in a 50 yard race where wins are often measured in a tenth or a hundredth of a second.”

The investigation serves as the latest chapter in Paxton’s aggressive pursuit of protecting women’s sports.

In February, the attorney general’s office sought a temporary injunction against the National Collegiate Athletic Association on the same grounds of deceptive trade practices.

A Lubbock district judge denied the request for a temporary injunction in March. However, the case is still ongoing, and its final result remains to be determined.
