NORRISTOWN - Bill Cosby is back in court for a second day of a crucial pretrial hearing in his Pennsylvania sexual assault case.

The 79-year-old entertainer returned to court Wednesday. He is facing charges from a 2004 encounter with a woman at his suburban Philadelphia home.

Prosecutors are asking a judge to permit testimony from 13 other women who also accuse Cosby of sexual assault. Prosecutors want to show that Cosby had a history of drugging and molesting women.

Cosby's lawyers say the women should be barred from taking the stand at his spring trial. They're expected to attack the accusers' credibility at Wednesday's hearing.
