Reginald ("Rex") King, who had been elected secretary of the short-lived New Mexico "National Assembly", dissolved by Remey in 1964. Unhappy about Remey's resistance to his leadership role in the United States, King eventually went to Italy where Remey was living, and had an apparently acrimonious meeting with him. Following this encounter, on 13 September 1969 Remey issued a letter denouncing King: "his station to be ever and eternally that of Satan for evermore". King switched his allegiance to Marangella when the latter advanced his own claims two months later.

This relationship, however, also soon broke down. King decided that Marangella had made "a number of faulty 'interpretations' of the Writings" and declared that Marangella "had ceased to fulfill the requirements of the office of guardian". He argued, indeed, that "neither Mason Remey nor Joel Marangella had in truth ever been guardians … because of the lack of lineal descendancy" (i.e., from Bahá'u'lláh). What Remey had actually been, King said, was "a regent", and King came to the "realization" that he himself "was in actuality the Second Regent…." [Mason Remey and Those Who Followed Him]
