Assistant to the deputy for foreign affairs. In 1967, he contributed to a top-secret study of classified documents on the conduct of the Vietnam War that had been commissioned by Defense Secretary McNamara. These documents, completed in 1968, later became known collectively as the Pentagon Papers. He began to feel guilty over the death occurring in Vietnam and his involvement, so on June 13, 1971, he released the Pentagon Papers to the New York Times. On June 21, 1971, he was indicted for many violations, including stealing, but the Times were still allowed to publish the papers after a supreme court ruling upheld their freedom of press.
