U.N. Ambassador Linda Thomas-Greenfield told Al Sharpton’s National Action Network (NAN) on Wednesday that “the original sin of slavery weaved white supremacy into our founding documents and principles.” Thomas-Greenfield addressed the NAN’s 30th annual summit, praising Sharpton for a “lifetime of activism” and thanking him for “never backing down.” She did not mention Sharpton’s history of antisemitic, racist, and homophobic rhetoric, or his role in inciting riots against Jews.
