The American television network ABC has canceled its top-rated show, “Roseanne.” The network made its decision shortly after the show’s star, Roseanne Barr, published a racist tweet. Early Tuesday, Barr wrote on Twitter, “muslim brotherhood & planet of the apes had a baby=vj.” “VJ” is Valerie Jarrett, who served as an adviser to former President Barack Obama and his wife, Michelle. She is African American. Barr’s tweet suggested she was a cross between the Muslim Brotherhood and the movie “Planet of the Apes.” Barr made note of Jarrett in answer to Twitter comments about conspiracy theories during Obama’s presidency. Conservative Twitter users had brought up Jarrett as being connected to those conspiracies. Social media users immediately criticized Barr’s tweet. She later deleted it.
