Corrections Corporation of America is pushing to get a forensic auditing report declared inconclusive after the auditors found the private prison company understaffed an Idaho prison by more than 26,000 hours.

The Idaho Department of Correction hired KPMG to conduct the audit last year after an Associated Press investigation showed that the company sometimes claimed its guards worked as much as 48 hours straight in order to fulfill staffing requirements.

CCA spokesman Steve Owen says the audit is rife with errors and overestimates the staffing shortfalls by more than a third. Owen says the company has hired an attorney to deal with Seattle-based KPMG directly in hopes of reaching an agreement that the report was inconclusive.

The report could impact the Tennessee company's other government relationships. Idaho corrections officials say prison leaders in several states and the U.S. Department of Justice have asked for copies of the audit.
