The top lobbyist on behalf of the District's red light camera contractor ACS also receives hundreds of thousands of dollars from the very city he is lobbying.

ACS has paid $500,000 to lobbyists who make political donations to Washington, D.C. city officials. Max Brown, a former aide to District Mayor Anthony Williams, is one of ACS' top lobbyists.

Since 2001, Brown's firm, Group 360, has received $688,000 from the D.C. government agencies, half if this amount coming from no-bid contracts. The majority of the money also comes from the city's Chief Technology Officer -- the same city official he was paid by ACS to lobby on behalf of red light cameras.

"I am a bloodhound when it comes to chasing contracts. And on the lobbying stuff, I am a Sherpa making sure that people don't step into a crevasse," Brown said in an interview.
