GM lost her bid on Wednesday to exclude a psychologist who has studied the "grooming" of sexual crimes victims from testifying at her upcoming trial.
Prosecutors have said they may call Lisa Rocchio, a psychologist who specializes in treating patients who have suffered sexual abuse, as a witness at the trial.
During the hearing, Rocchio said adolescents were particularly likely to disclose sexual abuse later in life. She said false allegations of sexual abuse can occur, but that they represent a "very small minority" of accusations.
GM’s lawyers said Rocchio's opinions are inadmissible, arguing they were based mainly on her personal experience as a practitioner and lacked scientific backing. They plan to call their own experts who would argue that the suggestion GM committed "grooming by proxy" - by winning the alleged victims' trust in order to manipulate them into having encounters with Epstein - had no support in the scientific community.
Following questioning, Judge Nathan said she would largely allow Rocchio's testimony, in a blow to GM's defense.
