Paul L. Williams, in a 2003 book entitled "The Vatican Exposed", claimed that US State Department documents confirmed that Siri had been elected pope in 1958 as Gregory XVII. According to Williams, however, the election was quashed not by a Judeo-Masonic conspiracy, but by fear of the Soviet Union. Roncalli, he claims, was known as the "pink priest" because of his ties with both the French and Italian Communist parties, while Siri was "rabidly anti-Communist". Siri received the requisite number of votes on the third ballot, and was elected as Gregory XVII, but "the French cardinals annulled the results, claiming that the election would cause widespread riots and the assassination of several prominent bishops behind the Iron Curtain." It was then decided to elect Cardinal Federico Tedeschini, but as he was too ill, Roncalli was elected instead. Williams cited "Department of State secret dispatch, 'John XXIII,' issue date: November 20, 1958, declassified: November 11, 1974" and "Department of State secret file, 'Cardinal Siri,' issue date: April 10, 1961, declassified: February 28, 1994" in support of his claims. In subsequent editions, however, the references were changed to simply "F.B.I. source".
