Over that week, more questions have been raised about the Houston lobbyist's professional and political activities. While the spotlight shined first on Payne's connections to President Bush, Vice President Cheney and other top administration officials -- and his attempt to raise cash for the George W. Bush Presidential Library and Museum -- attention has now shifted to the relationship between Payne and presumptive presidential nominee John McCain's top foreign policy adviser, Randy Scheunemann.

Scheunemann lobbied in Washington on behalf of Payne's companies, Caspian Alliance, which works with Central Asian regimes on energy projects. (The London Times reported that Caspian Alliance was providing advice to the Kazakh state-owned oil and gas company, KazMunayGas.)
