Insurance company USAA has tapped ad agency MullenLowe U.S. to handle its advertising business. The company fired its former agency Campbell Ewald after one of the agency’s creative directors sent out a racist email that was published on Adweek’s AgencySpy website in January. The email, sent to colleagues, promoted a "Ghetto Day in San Antonio" and that would involve ghetto music, Malt 45s at lunch, ghetto terminology, and drugs and prostitution.
