The 78-year-old comedian was charged this week with drugging and sexually assaulting a woman in 2004 inside his home near Philadelphia. It's the first criminal case brought against Cosby out of the torrent of allegations that destroyed his good-guy image as America's Dad.

Cosby's attorney has said the charge is unjustified and predicted her client will be exonerated.

Cosby is free on $1 million bail pending trial.
