Pennsylvania (Reuters):  A judge ruled on Friday that a second woman who said comedian Bill Cosby sexually assaulted her would be allowed to testify at his upcoming trial in Pennsylvania on charges he sexually assaulted a former employee of Temple University.

About 50 women have accused Cosby , 79, of sexual assault. But the accusation from 2004 by Andrea Constand, the former university employee, is the only one to result in a criminal prosecution. Cosby has denied any wrongdoing, but the accusations have shattered his image as an icon of family-friendly entertainment.

Constand worked with the women's basketball team at Temple University, where Cosby , a university alumnus, befriended her. She says Cosby drugged her and sexually assaulted her when she visited him at his home in Pennsylvania. Cosby says the encounter was consensual.
