[2] Eringer freelanced for the FBI's Foreign Counter-Intelligence Division[3] to assist with the apprehension of Edward Lee Howard, an ex-CIA officer who defected to the Soviet Union in 1985.

The graduate-level program included field-trips to places such as the U.S. Army Russian Institute in Garmisch, Germany, which led to his writing a feature article, "U.S. agents learn ropes at 'school of spies'" (1986), for the Toronto Star.

[10] As a Washington D. C. based literary agent and book consultant in the 1990s,[1] Eringer found himself working a controversial assignment for Clair George, a former deputy director of Operations of the CIA who was convicted on one count and later pardoned in the Iran-Contra scandal.

[11] Upon reading, Kenneth Feld (Ringling Bros. and Barnum & Bailey Circus) took umbrage to her portrayal of his parents and hired Clair George as a consultant to mitigate damages that the proposed book might cause the family and business.

"[16] On January 18, 2004, the St. Petersburg Times retrospectively reported that Janice Pottker had filed a complaint against the Feld family, Clair George, and Robert Eringer in 1999, seeking $120 million for invasion of privacy, interference in business relationships, infliction of emotional distress, fraud, conspiracy and breach of contractual obligations.

[20] One of the Monaco Intelligence Service's (MIS) early recommendations was to deny the renewal of Sir Mark Thatcher's residency card due to a troubling background check.

[31] As described by Nice RendezVous, MIS vetted Cabinet Director, Jean-Luc Allavena was dismissed in November 2006, and replaced in favor of the serving General Secretariat, Georges Lisimachio.

[22] The Palace of Monaco portrayed the court case as a blackmail attempt to "exploit the US judicial system to generate publicity to forward his extortionist agenda" by a "shakedown artist".

[1] Eringer however, had already filed a thirty-four page declaration, detailing his duties and findings[22][37] with the Superior Court of California, County of Santa Barbara (Case No., 1339892), on October 5, 2009.

The court determined that "according to his own attorneys and affidavit, Eringer's assignments" for the Principality were "not the type of employment private parties can undertake" and therefore fell within the Foreign Sovereign Immunities Act of 1976 (FSIA).
