The sex trafficking trial against Sean "Diddy" Combs is set to begin May 5, a judge announced yesterday. The trial is expected to last about a month, but prosecutors said the length could change if more charges are added. Combs is already charged with sex trafficking by force, transportation to engage in prostitution and racketeering conspiracy. Prosecutors allege he ran an "enterprise that he engaged in sex trafficking, forced labor or, kidnapping, arson and other crimes," according to the indictment unsealed last month.
