WASHINGTON – Sandia Corp. and its parent company, Lockheed Martin, will pay the federal government a $4.8 million fine for using tax dollars to lobby Congress and federal agencies for renewal of its $2.4 billion contract with the Department of Energy in violation of federal law. A report by the Department of Energy’s Office of Inspector General in 2014 concluded Lockheed Martin wrongfully used federal funds provided to Sandia for lab operations to lobby for the no-bid contract extension it ultimately received.
