The inspector general's role is to investigate and address fraud, waste, abuse, and wrongdoing in any executive branch agency.

The woman said she never wanted to come forward. But she said Hill's repeated denials were frustrating.

Indiana University says a review of sexual misconduct cases handled by its former student ethics director has found they were conducted without "bias or undue influence."
