American Idle: The five-bus caravan set to transport Democrats to their retreat in Williamsburg, Va., on Wednesday had some people fuming. The buses sat waiting outside the Longworth House Office Building for more than an hour with their diesel engines running, sources tell HOH. GOP staffers gleefully noted to HOH that the gas-guzzling tour buses were surely kicking up plenty of fumes while waiting for members of the party that has made environmental friendliness its signature. In fact, as the bus engines were reportedly purring, the Energy Independence and Global Warming Committee was holding a hearing inside the Longworth Building on global warming.
