After falling off the list of the 50 highest-grossing lobbying practices for 2008, Arent Fox jumped 73% with $10.7 million in revenue last year, the largest increase of any firm on the Influence 50 survey.

Arent Fox’s rebound was tied to work it picked up as a result of the faltering economy. Its lobbyists worked with clients seeking a piece of stimulus funding and they also repped car dealers trying to blunt the fallout from the General Motors and Chrysler bankruptcies.
