Bill Cosby's lawyers fight to block evidence from other accusers

Bill Cosby's lawyers are fighting to block a parade of women from giving evidence against him at his sexual assault retrial, calling them "ancient allegations" that would prejudice the jury against him.

Stung by a hung jury the first time around, prosecutors are pushing to widen the scope of Cosby's April retrial to cast the 80-year-old comedian as one of the biggest serial predators in a Hollywood suddenly aware of sexual misconduct in the #MeToo era.
