Brendan Paul, a former assistant to Sean Combs who was arrested last year amid federal raids, testified on Friday at the music mogul’s trial that he obtained drugs and prepared hotel rooms for nights of sex and partying as part of his job.

While Mr. Paul was a low-level employee — his duties included packing bags and coordinating meals — he also became one of the most prominent members of Mr. Combs’s entourage in March 2024, when he was charged with cocaine possession after sweeping searches of Mr. Combs’s properties.

On the day of the raids, which involved searches of two of Mr. Combs’s homes, Mr. Paul was at a Florida airport with the mogul, en route to a Combs family vacation in the Bahamas. Federal agents intercepted the group and found cocaine in a bag that Mr. Paul was carrying. Mr. Paul testified that he found the drugs — amounting to 0.7 grams — in Mr. Combs’s room early that morning and had forgotten about it as he was packing for the trip.

Mr. Paul, who had been working for Mr. Combs for about 18 months at the time, testified that he did not tell law enforcement that it was Mr. Combs’s cocaine.

“Why not?” a prosecutor, Christy Slavik, asked Mr. Paul.

“Loyalty,” he replied.

The case against Mr. Paul was dropped last year after he completed a drug intervention program.
