Corroborated allegations that Mr. Bolton's first wife, Christina Bolton, was forced to engage in group sex have not been refuted by the State Department despite inquires posed by Hustler magazine publisher Larry Flynt concerning the allegations. Mr. Flynt has obtained information from numerous sources that Mr. Bolton participated in paid visits to Plato's Retreat, the popular swingers club that operated in New York City in the late 1970s and early 1980s.
Mr. Flynt has contacted the State Department asking that they confirm or deny the allegations of Mr. Bolton's prior conduct concerning his wife and the alleged paid visits to Plato's Retreat. He has also called upon the Senate Foreign Relations Committee to conduct an inquiry into the very serious evidence concerning his first wife's fear of him.
Neither the State Department nor the Senate Foreign Relations Committee has yet responded to Mr. Flynt's inquiries.
Yes, I know Flynt makes this whole thing questionable.
