The women who have accused GOP contender Herman Cain of sexual harassment have agreed to hold a joint news conference to air their stories, one of their attorneys said Wednesday, a move that could fuel a controversy that has dogged the businessman’s campaign for more than a week.

Joel P. Bennett, who represents federal employee Karen Kraushaar, 55, said in an interview that he was planning the news conference with Gloria Allred, who represents Chicago homemaker Sharon Bialek, 50. Details of the joint appearance have not yet been worked out, Bennett said.
