"Empire" actor Jussie Smollett staged a racist, anti-gay attack on himself because he was unhappy about his salary and wanted to promote his career, Chicago's police superintendent said Thursday. Before the attack, Smollett also sent a letter that threatened him to the studio in Chicago where "Empire" is shot, Superintendent Eddie Johnson said. Smollett, who is black and gay, turned himself in Thursday to face accusations that he filed a false police report last month when he told authorities he was attacked in downtown Chicago by two men who hurled racist and anti-gay slurs and looped a rope around his neck, police said.
