More than 50 women have accused Bill Cosby of sexual assault. Now, for the first time, the 78-year-old comedian is facing felony criminal charges. The charges were brought by Montgomery County District Attorney Kevin Steele in Pennsylvania. They stem from a 2004 accusation by Andrea Constand, who says Cosby assaulted her when she was working at Temple University. Amy Sullivan, senior editor with Yahoo News, has more on the story.
