An American contracting company that was paid millions by the U.S. government to secure an Iraqi air base ignored reports of theft, sex trafficking, alcohol smuggling and repeated security breaches before firing the internal investigators that were looking into the violations, according to a report by the Associated Press on Wednesday.

The AP’s story is based on more than 100 documents, interviews with multiple company employees and the two fired investigators, Robert Cole and Kristie King. The violations, if proved, would likely amount to a serious breach of contract and — because Pentagon auditors were kept in the dark — could open up the company and its employees to possible legal action.
