Sen. John Cornyn, R-Texas, urged the International Olympic Committee (IOC) to cement its ban on biological males competing in women’s sports in a letter on Monday.

The IOC is set to enact a new policy that will prohibit transgender female athletes from competing against biological women, according to multiple reports. The policy is reportedly set to cover those with differences of sex development (DSD).

“Reports indicate the working group is moving towards a complete ban on biological males competing in female events, but that decision is not yet confirmed,” Cornyn wrote in a letter to IOC president Kirsty Coventry. “I urge the IOC to move swiftly toward a clear and decisive policy that protects fair and safe competition for women and prohibits biological males from competing in female categories.”

Cornyn underscored the need for resolution to ensure the integrity of women’s sports with the 2026 Winter Olympics approaching and the 2028 Summer Olympics around the corner.

“With the Winter Games rapidly approaching in February and preparation well underway for the 2028 Summer Olympics in Los Angeles, timely action is essential,” Cornyn added. “As the IOC continues its deliberations, this issue has become a global policy concern and a question of athletic integrity.

“In the United States, President Trump honored his unwavering commitment to women and girls with the issuance of Executive Order 1420: Keeping Men Out of Women’s Sports. His action reaffirmed the longstanding belief that women’s sports must be preserved for biological females.

“I applaud your commitment to addressing this issue and respectfully urge the International Olympic Committee to finalize the ban on biological males competing in female sports, without delay. Thank you for your attention and dedication to protecting women’s athletics.”

The new policy is reportedly expected to be announced in February just ahead of the Winter Olympics.

Coventry called for “protecting” the women’s category in June and there was “overwhelming support” from IOC members to do the same.

“We understand that there’ll be differences depending on the sport … but it was very clear from the members that we have to protect the female category, first and foremost to ensure fairness,” Coventry said at the time.

“But we need to do that with a scientific approach and the inclusion of the international federations who have already done a lot of work in this area.”
