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.

Three dozen potential jurors were questioned by Judge Arun Subramanian about their answers on a questionnaire meant to help determine if they could be fair and impartial at a trial that will feature violent and sexually explicit videos. Opening statements and the start of testimony are scheduled for next week.

The judge gave the would-be jurors a brief description of the sex trafficking and racketeering conspiracy charges against Combs, telling them he’d pleaded not guilty and was presumed innocent.

By the end of the day, the jury pool was half its size as some were excluded for personal reasons such as inability to endure a trial projected to last two months or because their opinions or past experiences would make it difficult for them to remain objective.

A similar number of jurors was expected to be questioned on Tuesday. A jury was not expected to be chosen before Wednesday.

Throughout Monday, Combs, 55, sat with his lawyers in a sweater over a white collared shirt and gray slacks, which the judge had allowed rather than jail clothing. He’s been held in a grim federal lockup in Brooklyn since his arrest last September. His hair and goatee were almost fully gray because dye isn’t allowed in jail.

Unlike other recent high-profile celebrity trials, Combs’ court case won’t be broadcast live because federal courtrooms don’t allow electronic recordings inside — meaning courtroom sketch artists serve as the public’s eyes in the courtroom.

If convicted of all charges, he could face up to life in prison.

Several prospective jurors indicated they’d seen news reports featuring a key piece of evidence in the case: a video of the hip-hop mogul hitting and kicking one of his accusers in a Los Angeles hotel hallway in 2016. One prospective juror described a still image she saw from the video as “damning evidence.” That woman was rejected from consideration.

After another juror was dismissed, Combs asked for a bathroom break, telling the judge, “I’m sorry your honor, I’m a little nervous today.”

One prospective juror said she had posted a “like” to a video put on social media by a comedian who included references to large amounts of baby oil found by law enforcement in one of Combs’ homes. She was not dismissed.

The 17-page indictment against Combs — which reads like a charging document filed against a Mafia leader or the head of a drug gang — alleges that Combs engaged in a two-decade racketeering pattern of abusive behavior against women and others, with the help of people in his entourage and employees from his network of businesses.

Prosecutors say women were manipulated into drug-fueled sexual performances with male sex workers that Combs called “Freak Offs.” To keep women in line, prosecutors say Combs used a mix of influence and violence: He offered to boost their entertainment careers if they did what he asked — or cut them off if they didn’t.
