The Texas attorney general has sued an adult swimming program after two transgender women were allowed to compete at a meet this spring in San Antonio, with one placing first in several events. The suit alleged that U.S. Masters Swimming undermined the trust of consumers through “false, deceptive, and misleading practices" because it said the other swimmers faced what it described as an unfair disadvantage in the Spring Nationals competition in April. U.S. Masters Swimming said in a statement that it has been cooperating fully with Attorney General Ken Paxton's investigation, which comes as a nationwide battle over the participation of transgender athletes has played out at both the state and federal levels.
