CBS ByJENNIFER HOAR AP November 8, 2006, (excerpts) "Bill Cosby settled a civil lawsuit filed by a woman who said the entertainer drugged and sexually assaulted her at his home outside Philadelphia."--"The federal judge presiding over the case earlier denied Cosby's request for a gag order and the plaintiff's request to shield the names of a dozen other women who say Cosby assaulted them."
