Sean “Diddy” Combs pleaded not guilty Friday to a superseding indictment which added accusations that the hip-hop mogul forced employees to work long hours and threatened to punish those who did not assist in a two-decade sex trafficking scheme. Combs, who appeared in a downtown Manhattan courtroom with newly gray hair and a gray beard, entered the New York court in a khaki two-piece jail uniform. He smiled when he saw members of his family seated in the courtroom. | CBS News
