Mr Berger contacted the "Restorationists" (members who consider themselves RLDS) in April 2017, through an email sent to Joseph F Smith at a website founded and maintained by Bob Moore. That email is found here:

Within months of that initial contact, which intended to bring the Restorationists under the plans of Mr. Berger, a group identifying themselves as "Quorum of Restoration Apostles" issued a "Detailed Response to the Brazilian Testimonies", an extensive 44 page scriptural counter to the claims of Mr. Berger. https://thesealedbookofmormon.org/restoration-apostles/
