Bill Cosby’s longtime onscreen wife Phylicia Rashad has come out swinging against the sexual assault allegations dogging her former co-star, saying they are part of an “orchestrated” smear campaign to keep the comedian off television.

Some 20 women—including supermodels Beverly Johnson and Janice Dickinson—have accused Cosby of sexual assault. The comedian, who has not been criminally charged, has denied assaulting the women and also has accused one of trying to extort him.
