NASCAR denounced its association with the “Let’s go, Brandon” political cry being used across the country as an insult directed at President Joe Biden. Steve Phelps, NASCAR’s president, said Friday the top motorsports series in the United States does not want to be associated with politics “on the left or the right.”

Phelps also said NASCAR will pursue action against any illegal use of its trademarks on merchandise boasting the slogan. Retired baseball star Lenny Dykstra posted a photo on Twitter this week of a man eating breakfast at a New Jersey hotel wearing a black “Let’s go, Brandon” shirt alongside NASCAR’s trademarked color bars.

“We will pursue whoever (is using logos) and get that stuff,” Phelps said. “That’s not OK. It’s not OK that you’re using our trademarks illegally, regardless of whether we agree with what the position is.”
