The Wall Street Journal has obtained internal Pentagon documents that show the Army is preparing to allow Halliburton to keep several billion dollars for work done in Iraq even though the company can’t document how the money was spent. According to the report, Halliburton subsidiary Kellogg Brown & Root has so far billed about $12 billion in Iraq, and about $3 billion of that remains disputed by government officials. Meanwhile the Army has agreed to a Pentagon investigation into claims by a top contracting official that a Halliburton subsidiary unfairly won no-bid contracts worth billions of dollars for work in Iraq and the Balkans. The chief contracting officer of the Army Corps of Engineers, Bunnatine Greenhouse, said in a letter the Halliburton deals put at risk “the integrity of the federal contracting program as it relates to a major defense contractor.” Attorneys for Greenhouse are now seeking whistleblower status for the Army employee.
