The U.S. Olympic and Paralympic Committee tells the federations overseeing swimming, athletics and other sports that it has an "obligation to comply" with an executive order issued by President Trump.

President Trump signed an executive order Wednesday aimed at preventing transgender athletes from competing in women's sports. It's the latest in a series of actions focused on "gender ideology."

The International Chess Federation will stop allowing transgender women to participate in women's tournaments. The group said changing genders has a "significant impact" on a player's status.
