Just to be totally anal, if you are referring to Max Larson, he is not a member of the GB. He is much more powerful than that, as he is the President of the WTB&TS of New York, and a member of the newly formed U.S. Branch committee. But since he is not of the anointed, he is not on the GB.
I keep up on Max cause I sat next to him for my one and only week spent at Bethel. At the time I did not realize just how big a player he was. He was at our DC last year.
