NEW YORK >> The federal sex trafficking trial of Sean “Diddy” Combs, whose wildly successful career has been dotted by allegations of violence, began 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 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 in September. His hair and goatee were almost fully gray because dye isn’t allowed in jail.
