Forensic psychiatrist who testified at Bill Cosby's trial will be a prosecution witness at Harvey Weinstein's

Harvey Weinstein and Bill Cosby

(CNN)A forensic psychiatrist who testified for the prosecution in the trial of Bill Cosby will be a witness for the prosecution at Harvey Weinstein's sexual assault trial scheduled for September.

Dr. Barbara Ziv, a professor at Temple University and a member of the Pennsylvania Sexual Offenders Assessment Board for nearly 20 years, confirmed to CNN she will be a witness for the prosecution in the Weinstein case after documents previously withheld from the public were unsealed by New York's Supreme Court on Tuesday.
The movie mogul, whose downfall sparked the #MeToo movement, is accused of raping a woman in a New York hotel room in 2013 and forcibly performing oral sex on another woman at his Manhattan apartment in 2006.
He faces five felony charges: two counts of predatory sexual assault, one count of criminal sexual act in the first degree, and one count each of first-degree rape and third-degree rape. A sixth felony charge was dismissed in October after a New York police detective was found to have mishandled evidence.
    Weinstein has denied all accusations of nonconsensual sex made against him and has pleaded not guilty to all charges against him.
    Cosby, the 81-year-old comedy icon, was sentenced in September to three to 10 years in a state prison for drugging and sexually assaulting Andrea Constand at his home 14 years ago.
    At Cosby's trial, Ziv testified about how sexual assault victims behave, saying that "delayed reporting" to authorities is the norm, not the exception.
    "Delayed reporting can go from days to weeks to months to years," she said then. "We blame victims for not being the kind of victim that we think they should be. It's part of the rape myth that victims report promptly and display a certain set of symptoms."
    In their case against Weinstein, prosecutors plan to use Ziv for two purposes, their notice of expert testimony, a document filed with the court in January but unsealed Tuesday, outlines.
    First, they plan to have Ziv testify about information beyond the average juror's knowledge: Why victims may delay disclosing a sexual assault, factors that determine whether and how a victim may interact with their attacker after an assault has happened, and why a victim may lack signs of an outward trauma after an assault.
    And just as she did in the Cosby trial, prosecutors say Ziv's testimony in the Weinstein case "is necessary to dispel several myths about sexual assault that continue to be prevalent even in today's society," according to their filing. Those myths, the DA's office say, include: victims are usually raped by strangers, they promptly report an assault to authorities, that they display symptoms of trauma and finally, that victims never communicate with their attackers.
