Former U.S. women’s soccer star Megan Rapinoe and WNBA legend Sue Bird were among the current and former athletes who signed Athlete Ally’s letter to the NCAA urging the organization to forgo enacting a policy that would bar trans athletes from competing in women’s sports.

The letter from the LGBTQ advocacy group came after more than a dozen House Republican lawmakers urged NCAA president Charlie Baker to ban transgender athletes from competing in women’s sports, following a policy set by the National Association of Intercollegiate Athletics earlier this month. The lawmakers cited Lia Thomas’ national championship in 2022, which marked Thomas as the first trans woman to win an NCAA national title.
