Raffaello Follieri, 30, pleaded guilty in September to fraudulently obtaining US$2.4 million by leading investors to believe he had Vatican connections that enabled him to buy the Roman Catholic Church's unwanted US properties at a discount.
Follieri had good connections to both McCain and Rick Davis, for whom he had promised to "deliver Catholic votes", and was the host of John McCain's 70th birthday party, celebrated onboard the yacht of another dodgy character - a Russian oligarch who pretty much owns the tiny state of Montenegro.
Deripaska is himself involved in some political scandal right now - involving both a high level Labour Party cabinet minister, Lord Peter Mandelson who was one of Tony Blair's closest advisors and the current shadow chancellor, the Conservative Party's George Osborne. Both McCain and his campaign manager, Rick Davis have dubious ties to Deripaska too. Other McCain campaign advisers, lobbyists to a man, have their own shady connections.
