When Jaylen Brown tweeted “energy” earlier Sunday when talking about Kyrie Irving supporters, the backlash came immediately. In the video that Brown mentioned on Twitter, there was a large group of Black Hebrew Israelites congregating outside the Nets’ Barclays Center. Irving had been reinstated from his suspension after eight games, and the group gathered in support of Irving on Sunday.

Among the group gathered in Brooklyn, some people reportedly handed out flyers with Radical Hebrew Israelite propaganda. The Radical Hebrew Israelite are categorized as a hate group, per the Southern Poverty Law Center. After hearing criticism for his initial tweet, Brown tweeted an explanation a few hours later.
