In one of his volumes of an internal report written between 1974 and 1984, CIA Chief Historian Jack Pfeiffer criticized the Taylor Committee's investigation, as it held the CIA primarily responsible for the Bay of Pigs fiasco. At the end of the fourth volume, Pfeiffer laments that Taylor had a hand in perpetuating the idea that "President Kennedy was a white knight misled by overconfident, if not mischievous, CIA activists."[citation needed]
