The OIG investigated allegations that officials from the Bureau of Reclamation (USBR) and the U.S. Department of the Interior, Office of the Solicitor (SOL), obstructed an administrative inquiry into alleged sexual misconduct by a USBR official. The complainant alleged that USBR and SOL officials withheld information, attempted to influence witnesses by holding meetings to discuss the inquiry, and tried to stop the inquiry. The complainant further alleged that these officials provided advice to the inquiry while also advising regional management on how to address the alleged misconduct.
