A tip came from the FBI, who were tapping Ellsberg’s phone calls, specifically a phone call between Ellsberg and his psychiatrist Lewis Fielding where Ellsberg said he was ‘immensely relieved that he had completed his task’. Other reports said that Ellsberg and his wife indulged in hallucinogenic drugs and orgies, suggesting they were part of the hippy scene, and that Ellsberg had a girlfriend from Sweden, a major entry point for Soviet agents to get into Western Europe. When news came in that the Pentagon Papers had been supplied to the Soviets before the New York Times began publishing them alarm bells started to ring. People noted that Ellsberg had attended Cambridge University, where the members of notorious Soviet spy ring were recruited.
