A notable source of modern conspiracy theories which involve the Jesuits is "Vatican Assassins" by Eric Jon Phelps. It is said to allege that Newt Gingrich is "one of the ten most dangerous, Jesuitical politicians of the Pope's 'Holy Roman' Fourteenth Amendment, Cartel-Corporate-Fascist, Socialist-Communist American Empire" and it also alleges that the Jesuits played a role in the Assassination of John F. Kennedy. Skeptic Bob Blaskiewicz also claims that Phelps told him that the alleged "Grey aliens" are not aliens but creations of Jesuit science.
