The U.S. Olympic and Paralympic Committee will allow raised fists and kneeling during the national anthem at Olympic trials. That will preview a contentious policy the USOPC expects to stick to when American athletes head to Tokyo this summer. The USOPC released a nine-page document to offer guidance about the sort of “racial and social demonstrations” that will and won’t be allowed by the hundreds of athletes who will compete for spots on the U.S. team in various sports. The guidance came three months after the federation, heeding calls from its athletes, determined it would not enforce longstanding rules that ban protests at the Olympics.
