LaRouche
Levy infiltrated the Lyndon LaRouche organization on a part-time basis from 1980–84 as a security consultant and supplied disinformation that convinced some of LaRouche's security staffers of plots against their leader. After Levy revealed his deception, the LaRouchians described him as a "chaos agent."
Levy has said that the JDO has a membership of 3,000 members, but monitors of Jewish extremist groups say only about a dozen people are actively involved at any one time. A 1992 feature in the Jerusalem Report notes that "Journalists and extremist-group monitors who have followed Levy's career say the Jewish Defense Organization exists mainly in his mind, that his hardcore following is at most a few dozen Orthodox teenagers."
