John McCain's chief foreign policy adviser, Randy Scheunemann, is known for his aggressive posture on foreign policy, having served as an architect of the Iraq war and, more recently, a fierce supporter of and lobbyist for the former Soviet nation of Georgia.
But apparently he takes the notion of cowboy diplomacy to a new level. A Democratic source tipped off the Huffington Post that back in 1997, when he was serving as a top adviser to Sen. Trent Lott, Scheunemann was arrested by Capitol Hill police for a gun violation.
According to a Washington Times article from February 1997, Scheunemann was spotted by a police unit with a shotgun case through the window of his car. They stopped him to ask if the case contained an actual gun. It did. Moreover, Scheunemann had several rounds of ammunition as well.
