The man being berated is Marty Rathbun, who spent two and a half decades in the church, rising to become a top official there before breaking away in 2004. On his blog, Rathbun writes that the people berating him in the video are three of the current top management personnel named Jenny Linson, Marc Yager, and Dave Bloomberg.
On Sunday evening, Rathbun posted this bizarre 2-minute video, a video he had taken earlier in the day while he was waiting at Los Angeles International Airport to catch a flight back to his home in Texas. Rathbun thinks the entire thing was a set up because Rathbun points out "there was only one carry-on bag for the three of them." The way they spoke was also very calculated and seems pretty clear it was well rehearsed.
