COLORADO SPRINGS, Colo. (AP) The U.S. Olympic and Paralympic Committee has effectively barred transgender women from competing in women’s sports, telling the federations overseeing swimming, athletics and other sports it has an “obligation to comply” with an executive order issued by President Donald Trump.

The new policy, announced Monday with a quiet change on the USOPC’s website and confirmed in a letter sent to national sport governing bodies, follows a similar step taken by the NCAA earlier this year.

The USOPC change is noted obliquely as a detail under “USOPC Athlete Safety Policy” and references Trump’s executive order, “Keeping Men Out of Women’s Sports,” signed in February. That order, among other things, threatens to “rescind all funds” from organizations that allow transgender athlete participation in women’s sports.

U.S. Olympic officials told the national governing bodies they will need to follow suit, adding that “the USOPC has engaged in a series of respectful and constructive conversations with federal officials” since Trump signed the order.

“As a federally chartered organization, we have an obligation to comply with federal expectations,” USOPC CEO Sarah Hirshland and President Gene Sykes wrote in a letter. “Our revised policy emphasizes the importance of ensuring fair and safe competition environments for women. All National Governing Bodies are required to update their applicable policies in alignment.”

The National Women’s Law Center put out a statement condemning the move.

“By giving into the political demands, the USOPC is sacrificing the needs and safety of its own athletes,” said that organization’s president and CEO, Fatima Goss Graves.

The USOPC oversees around 50 national governing bodies, most of which play a role in everything from the grassroots to elite levels of their sports. That raises the possibility that rules might need to be changed at local sports clubs to retain their memberships in the NGBs.

Some of those organizations for instance, USA Track and Field have long followed guidelines set by their own world federation. World Athletics is considering changes to its policies that would mostly fall in line with Trump’s order.

A USA Swimming spokesman said the federation had been made aware of the USOPC’s change and was consulting with the committee to figure out what changes it needs to make. USA Fencing changed its policy effective Aug. 1 to allow only “athletes who are of the female sex” in women’s competition and opening men’s events to “all athletes not eligible for the women’s category, including transgender women, transgender men, non-binary and intersex athletes and cisgender male athletes.”

The nationwide battle over transgender girls on girls’ and women’s sports teams has played out at both the state and federal levels as Republicans portray the issue as a fight for athletic fairness. More than two dozen states have enacted laws barring transgender women and girls from participating in certain sports competitions. Some policies have been blocked in court after critics challenged the policies as discriminatory, cruel and unnecessarily target a tiny niche of athletes.

The NCAA changed its participation policy for transgender athletes to limit competition in women’s sports to athletes assigned female at birth. That change came a day after Trump signed the executive order intended to ban transgender athletes from girls’ and women’s sports.

Female eligibility is a key issue for the International Olympic Committee under its new president, Kirsty Coventry, who has signaled an effort to “protect the female category.” The IOC has allowed individual sports federations to set their own rules at the Olympics and some have already taken steps on the topic.

Stricter rules on transgender athletes barring from women’s events anyone who went through male puberty have been passed by swimming, cycling and track and field. Soccer is reviewing its eligibility rules for women and could set limits on testosterone.

Trump has said he wants the IOC to change everything “having to do with this absolutely ridiculous subject.” Los Angeles will host the Summer Games in 2028.
