The Pentagon’s top watchdog has announced he won’t investigate rape allegations made by a former employee of the war contractor Halliburton and its subsidiary KBR. The alleged victim, Jamie Leigh Jones, says she was gang-raped by co-workers in Iraq. Jones has accused KBR and the U.S. government of covering up the crime. On Tuesday, Pentagon Inspector General Claude Kicklighter said he won’t look into the charges because the Justice Department still considers it an open case. Democratic lawmakers and Jones’s defense team both criticized the decision. A criminal probe has already lasted more than two-and-a-half years with no charges filed.
