The world's largest defense contractor has agreed to pay $4.7 million to settle charges that it illegally used government money. Top executives for Lockheed Martin - who were being paid by the federal government to run Sandia National Laboratories - ran a fierce campaign to lobby [government] officials for a seven-year extension of their contract, [and] urged them to close the bidding to competition. To clinch the contract extension, Sandia labs officials hired high-priced consultants - including Heather A. Wilson, the former New Mexico congresswoman, who allegedly was paid $226,000. Wilson was not just on Lockheed's payroll. From 2009 through 2011, she had consulting jobs for Lockheed and three other contractors managing the Energy Department's national lab, charging taxpayers a total of $450,000. But the contractors could not document her work, said [Energy Department Inspector General Gregory] Friedman, whose staff found that the justification for the billing did "not meet even minimum standards" for federal payments." Wilson ... left Congress in 2009. Jay Coghlan of Nuclear Watch New Mexico, called the deal a "slap on the wrist for the world's biggest defense contractor to pay," [and] wrote on the NuclearWatch blog Lockheed "engaged in deep and systemic corruption, including paying Congresswoman Heather Wilson $10,000 a month starting the day after she left office for so-called consulting services that had no written work requirements."
