Loydene Rambo filed a False Claims Act lawsuit alleging that, between 2005 and 2010, Fluor Hanford and Mission Support Alliance LLC (MSA) (a joint venture between Lockheed Martin Integrated Technology, LLC, Jacobs Engineering Group, and Wackenhut Services, Inc.) engaged in lobbying while managing the Department of Energy’s Hazardous Materials Management and Emergency Response (HAMMER) Center at the Hanford Nuclear Site. Rambo claimed that Fluor and MSA’s actions violated the Byrd Amendment, which prohibits contractors from using federal funds to influence or attempt to influence an executive agency or Congress in connection with federal contracts. Rambo alleged that Fluor and MSA spent approximately $670,000 in federal funds to hire outside lobbyists. In April 2013, Fluor settled the lawsuit for $1.1 million.
