(Here is a complete list of the allegations against Combs).

NEW YORK (AP) — The federal sex trafficking trial of Sean “Diddy” Combs, whose wildly successful career has been dotted by allegations of violence, began on Monday in New York City with jury selection that was briefly paused when the hip-hop entrepreneur said he was “a little nervous” and needed a bathroom break.

Ventura, a rhythm and blues singer known as Cassie, testified on Tuesday she acceded to participating for a decade in Combs' drug-fueled parties known as "Freak Offs," often fearful he could become violent if she didn't.
