The US Secret Service said late Friday that three more of its employees have resigned, bringing to six the number that have left the agency in connection with alleged misconduct involving prostitutes in Colombia last week before President Barack Obama's trip there. The Secret Service also said that a 12th employee had been implicated in the ongoing investigation into a night of partying on April 11-12 that embarrassed the United States and overshadowed Obama's participation in the Summit of the Americas last weekend. The agency's statement said that one employee had been cleared of “serious misconduct.”
