It is alleged that, in addition to his vast stash of bribes, Duke Cunningham (and maybe others) were treated to parties in a hospitality suite operated by Cunningham's defense contractor benefactors. Poker, cigars, liquor and hookers. It has been speculated that other Congressmen were involved in the parties, and that the #3 at CIA was in attendance. It has also been speculated, but denied, that Goss was in attendance while he was a Congressman.
That's the nutshell.
