John Green

Green announced in March that he planned to take leave from his post as a managing director at Ogilvy Government Relations to coordinate the McCain campaign's efforts with congressional Republicans. In recent years, the firm's clients have included European Aeronautic Defense & Space, which beat Boeing for a $35 billion Air Force tanker contract. Also, his firm represented Ameriquest Mortgage, one of the most notorious lenders in the current mortgage crisis.

This year, he is registered to lobby for 57 clients including Pfizer, United Health Care Group, the Carlyle Group and the American Petroleum Group.
