We initiated this investigation based on information we received while investigating U.S. Department of the Interior (DOI) Secretary Ryan Zinke’s use of noncommercial aircraft for U.S. Government travel. This investigation focused on whether Secretary Zinke abused his position by having his family members travel with him in Government vehicles, whether he asked that his wife, Lolita Zinke, be appointed as a DOI volunteer to legitimize her travel, and whether he requested a Government cell phone for her.
