This undated file photo released by U.S. Immigration and Customs Enforcement shows a water urn, one of many items looted from Saddam Hussein's palaces, that were recovered by federal investigators and formally repatriated to Iraq in a March 16, 2015, ceremony at the Iraqi consulate in Washington. Officials traced the urn to an American defense contractor who worked in Iraq and who acknowledged taking it. Laws prohibit the export and sale of antiquities that belong to foreign governments. The case was presented to federal prosecutors in Connecticut but they declined to file charges. (AP Photo/U.S. Immigration and Customs Enforcement, File)
