The Washington Redskins face renewed pressure to change their nickname, but this time protestors are targeting their sponsors, Adweek reported.

According to the report Wednesday, Nike, FedEx and PepsiCo each received letters signed by 87 investment firms and shareholders worth a combined $620 billion asking the companies to sever ties with the Redskins unless they change their controversial name. There has been more pressure in recent weeks to change their name given the social climate following the death of George Floyd in Minnesota.

The Redskins have contributed to some of that change, removing the name of former owner George Preston Marshall from their ring of fame. Marshall was the last NFL owner to integrate his roster, and did so only under pressure from the government to avoid losing a 30-year lease on federal land.

But Native American leaders want owner Dan Snyder to change the name, which the franchise has used since 1933. In the past, groups protested the name and tried to win in court. Those efforts failed. Now investors are appealing to the sponsors, something that one former high-ranking Redskins employee called “different.”
