Weinstein, 67, has pleaded not guilty to raping Mann and to sexually assaulting former production assistant Mimi Haleyi.
Mann accused Weinstein of raping her in a Manhattan hotel in 2013. She previously testified that the rape occurred in the course of an “extremely degrading” relationship with Weinstein that lasted for years.
Thomas Richards, a former friend and agent of Mann, a onetime aspiring actress, is expected to take the stand on Tuesday.
