Philadelphia Mayor Jim Kenney announced the abrupt resignation of his city's police commissioner Richard Ross Tuesday amid reports of sexual harassment and racial and gender discrimination within the police department. Calling himself "disappointed," Kenney, in a statement, said Ross has been "a terrific asset to the Police Department and the City as a whole." "New allegations of sexual harassment as well as gender and racial discrimination among the rank and file have recently been brought to my attention," Kenney added.
