NASCAR has banned displays of Confederate flags from its events, where the white supremacist symbol has long been a fixture. The move came just two days after NASCAR’s only top-tier African American driver, Bubba Wallace, made this comment on CNN.

Bubba Wallace: “No one should feel uncomfortable when they come to a NASCAR race. So it starts with Confederate flags. Get them out of here. They have no place for them.”

This week, Wallace wore a T-shirt reading “I can’t breathe” as he debuted his car’s new paint scheme: all black, with the hashtag “#BlackLivesMatter” stenciled along the side.
