On January 31, 2010, three current and former U.S. government officials confirmed the Justice Department is investigating whether officials of Blackwater Worldwide tried to bribe Iraqi government officials in hopes of retaining the firm's security work in Iraq after the shooting in Nisour Square in Baghdad, which left 17 Iraqis dead and stoked bitter resentment against the United States. The officials said that the Justice Department's fraud section opened the inquiry late in 2009 to determine whether Blackwater employees violated a federal law banning American corporations from paying bribes to foreign officials. In 2012 the Department of Justice closed the investigation without filing any charges.
