Paul Gregory is a research fellow at the Hoover Institution and the Cullen Professor Emeritus in the department of economics at the University of Houston. He’s also the author of a new book, The Oswalds: An Untold Account of Marina and Lee, a fascinating account of the relationship he developed with Marina and Lee Oswald in the summer of 1963, when Gregory was 21 years old.

Gregory went off to college at the University of Oklahoma in the fall of 1963 and didn’t see Lee or Marina again. Then, one fateful day in late November, Gregory was shocked to see a news report identifying Oswald as the lead suspect in the assassination of John F. Kennedy. Gregory soon faced interrogations by the Secret Service. Later, he would testify before the Warren Commission. In this interview, recorded in February 2023, Gregory recalls these events and, as a scholar and skilled researcher, debunks several assassination conspiracy theories by demonstrating that Lee Harvey Oswald indeed killed Kennedy and acted alone — that the Oswald he once called a friend had the motive, the intelligence, and the means to commit one of the most infamous crimes in American history.
