Prosecutors with the Manhattan U.S. Attorney's office want to call Dawn Hughes, a psychologist, to testify about how victims of sexual abuse may sometimes remain loyal and committed to their perpetrator and stay in relationships with them due to emotional manipulation or a fear of violence. Hughes has testified in other high-profile sex trafficking cases, including R&B singer R. Kelly's trial in 2021.
Prosecutors say Hughes' expertise is necessary to contextualize Combs' argument that victims willingly participated in "Freak Offs" given that they at times expressed affection for him and chose to stay with him.
"The defense will then argue that these victim responses are incompatible with the victim being a victim of abuse," prosecutors wrote in a court filing on Wednesday. "Dr. Hughes would testify that it is the dynamics of interpersonal violence that result in such behavior."
Alexandra Shapiro, a lawyer for Combs, said at an April 18 court hearing that the government was improperly seeking to use Hughes' testimony to bolster the credibility of the alleged victims who are expected to testify against him.
"They're going to use this to say that this expert told them that essentially they should believe these people," Shapiro said.
Friday's hearing is due to begin at 11 a.m. EDT (1500 GMT).
Opening statements in Combs' trial, which is expected to last between eight and 10 weeks, are scheduled for May 12.
Also known during his career as Puff Daddy and P. Diddy, Combs is credited with helping turn rappers and R&B singers such as Mary J. Blige, Faith Evans, Notorious B.I.G. and Usher into stars in the 1990s and 2000s.
But prosecutors have said his success concealed a dark side. They say he used threats of physical violence and cutting off financial support to coerce women to participate in the "Freak Offs" with male sex workers. Prosecutors say the performances were often days-long, drug-fueled events during which Combs would sometimes record and masturbate.
Combs has been jailed in Brooklyn since September. He faces the possibility of decades in prison if convicted.
