A new report by Rep. Henry Waxman discloses some of Halliburton/KBR’s billing shadiness in Iraq. “In one case, the government’s contracting officials reported that KBR attempted to inflate its cost estimates by paying a supplier more than it was due. In another, KBR cut its cost estimates in half after it was pressed on its true expenses. In a third, KBR billed for work performed by the Iraqi oil ministry.“
