U.S.A. Fencing posted a new policy for transgender athletes on Friday that will take effect on Aug. 1. Those new rules still allow trans women to compete, but only in the men’s category. The policy says that nonbinary athletes, transgender men and intersex athletes will also be limited to competing in the men’s category. The Olympic committee said in its new policy that it was “committed to protecting opportunities for athletes participating in sport,” and that it would work with the International Olympic Committee, the International Paralympic Committee and the national governing bodies of every Olympic sport “to ensure that women have a fair and safe competition environment consistent with Executive Order 14201 and the Ted Stevens Olympic & Amateur Sports Act.” The committee had not announced any plans to comply with Mr. Trump’s order. Before the new policy was posted, the committee had stayed away from the issue as the 2028 Olympics in Los Angeles inched closer. Instead, it had delegated decisions about transgender athlete eligibility to the national governing bodies of each sport. The Olympic committee has 54 member organizations, according to its website. Before Monday, the committee’s transgender policy stated that the group was relying on “real data and science-based evidence rather than ideology.” “That means making science-based decisions, sport by sport and discipline by discipline, within both the Olympic and Paralympic movements,” the former policy said.
