 In the course of that investigation, evidence of espionage against the United States Government was uncovered.Aquino was then accused of helping Aragoncillo transmit classified United States documents regarding President Gloria Macapagal-Arroyo to her opponents in the Philippines, including both Joseph Estrada and current opposition leader Panfilo Lacson, who had been Aquino's superior in the police force.Under an eventual plea-bargain agreement, Aquino entered a plea of guilty to illegal possession of classified documents, but avoided the more serious charge of espionage that Leandro Aragoncillo received.
