The University of Pennsylvania (UPenn) has reversed its policy on transgender athletes in women's sports following pressure from the Trump administration. UPenn will ban biological men from competing in women's sports, issue an apology to female athletes, and strip transgender swimmer Lia Thomas of all titles and records she won while competing on the women's team. Lia Thomas, who competed for UPenn until 2022 and was the first openly transgender athlete to win a Division I title, will have his records erased in line with the university's renewed commitment to Title IX and fairness in women's sports. The decision has been praised by Education Secretary Linda McMahon and various Republican lawmakers, who credit the Trump administration's enforcement of Title IX and executive orders for the policy change. Former teammates of Lia Thomas have expressed relief and validation following the university's apology and policy reversal. Additionally, Florida's Attorney General has threatened legal action against U.S. Masters Swimming over its transgender athlete policies, demanding a ban on men competing against women in masters swimming events. Congressional Republicans are pushing legislation, including the Defend Girls Athletics Act, to codify protections for women's sports and restrict participation to biological females, emphasizing fairness and safety. The developments reflect ongoing national debates over transgender participation in sports and federal enforcement of related policies.
