The renowned Olympic protester has written a letter with an influential group of American athletes, calling on the IOC to put in place a new policy done in collaboration with athletes from across the globe.

Carlos joined the leadership of the U.S. Olympic and Paralympic Committee’s athlete advisory council in sending the open letter to the International Olympic and Paralympic committees on Saturday.

This month, with protests stemming from the killing of George Floyd spreading across the U.S., IOC President Thomas Bach said the athlete group would “explore different ways” opinions could be expressed during the games — while still “respecting the Olympic spirit.”

Also this week, the head of the Caribbean Association of National Olympic Committees came out in favor of a redrafting of Rule 50, arguing the oft-cited IOC notion that sports should be free of politics is not realistic.

USOPC leaders have said they are trying to expand the conversation about racial injustice, and are open to pressing for changes in Rule 50 — the IOC rule that bars protests on the medals stand and other inside-the-line venues at the games.
