Weinstein still faces charges in Los Angeles of rape and sexual assault of two women in 2013.
More than eighty women, including famous actresses, had accused him of sexual misconduct stretching back decades.

Miss Mann said that she found herself in an “extremely degrading” relationship with him that did not involve intercourse until he raped her in 2013.
She said he was a “Jekyll and Hyde” figure who could be charming in public but showed his dark side when they were alone.
Another one of Weinstein’s accusers, Sopranos actress Annabella Sciorra, told jurors that he raped her in her apartment one night in 1993 or 1994.
Her allegation was too old to be charged as a separate crime, but prosecutors used it in an attempt to demonstrate that the accused was a repeat sexual offender.
