Thomas G. Buchanan was an American journalist published in many countries, and the author of four published books:
- The Unicorn (a novel)
- Who Killed Kennedy?
- De getuigen sterven (The Witnesses Die – about the deaths of several witnesses to the JFK assassination)
- Big Brother – Ma vie revue et corrigée par le F.B.I.
(Big Brother – My life reviewed and revised by the F.B.I.)
In 1948, Thomas G. Buchanan was the first American journalist to be explicitly fired solely for his membership in the Communist Party. This triggered a long debate in the American Newspaper Guild about whether or not to support the civil rights of its communist members.
After being blacklisted as a journalist, Buchanan became the executive secretary of the Washington chapter of the Civil Rights Congress. It earned him being tabbed as a “key figure” by the F.B.I.
His book, Who Killed Kennedy?, was among the first to be published after the Kennedy assassination, and garnered enough attention in Europe that the C.I.A. director, John McCone, conferred with Chief Justice Earl Warren to encourage him to examine the book carefully so as to properly address any of its allegations. He thought that if this were not done, Buchanan’s conclusions would go unchallenged. When Warren suggested it might be worth having Buchanan give a deposition to the Commission, McCone discouraged that action, saying that Buchanan would likely use it as an opportunity to obtain more interviews to give his book more publicity. [Information obtained from declassified F.B.I. files — the F.B.I. agent who made the report was given an account of this exchange between McCone and Warren by McCone himself on May 19, 1964.]
