Casandra Ventura, known as Cassie, gives her second day of testimony as the prosecution’s key witness in the sex-trafficking trial of disgraced rap mogul Sean "Diddy" Combs. Cassie, the ex-girlfriend of the rapper, tells the court that Combs asked her to get into an inflatable pool filled with baby oil.

She continues to describe the abuse she endured during events she called “freak-offs,” saying Combs later used video recordings of the encounters to blackmail her.

Cassie alleges she repeatedly suffered from urinary tract infections as a result of the "freak-offs," to the point that she became immune to antibiotics. She testifies that Combs forced her to perform during her menstrual cycle and took away her possessions if she upset him in any way.

Combs faces charges of racketeering, sex trafficking, and transportation to engage in prostitution. The 55-year-old denies all charges. If convicted, he could spend the rest of his life in prison.
