Brooklyn Nets owner Joe Tsai is speaking out against his team’s star player, Kyrie Irving. Tsai issued a statement on Twitter on Friday, saying he condemns Irving for promoting an antisemitic film and book on his social media accounts.

“I’m disappointed that Kyrie appears to support a film based on a book full of anti-Semitic disinformation,” the Nets owner tweeted. “I want to sit down and make sure he understands this is hurtful to all of us, and as a man of faith, it is wrong to promote hate based on race, ethnicity or religion.”
