The International Olympic Committee relaxed some aspects of its protesting guidelines. Athletes are not allowed to protest during competitions and are not allowed to protest on the medal stands. Any kind of political statement will need to come right before events or while talking to the media.

The U.S. women’s soccer team, and other squads, knelt before their matches.
