n"> Bill Cosby was set to return to criminal court on Tuesday for the first time since his lawyers' failed effort to have the sexual assault charges against him thrown out. Prosecutors in Montgomery County, Pennsylvania, are expected to outline some of the evidence against Cosby, 78, who had been one of America's best-loved comedians before being hit by a wave of sex assault allegations. The former prosecutor, Bruce Castor, has said he agreed not to press charges in exchange for Cosby's testimony in a civil lawsuit filed by Constand.
