A Texas oil executive from Elon Musk’s government efficiency team has been given sweeping powers to overhaul the federal department that manages vast tracts of resource-rich public lands, but he hasn't divested his energy investments or filed an ethics commitment to break ties with companies that pose a conflict of interest, records show. Interior Secretary Doug Burgum recently directed Tyler Hassen, who lacks Senate confirmation and has no public administration experience, to reorganize the Interior Department, which oversees some 70,000 employees in 11 agencies including the National Park Service, Bureau of Land Management, Fish and Wildlife Service, Bureau of Reclamation, U.S. Geological Survey and the Bureau of Indian Affairs. Before joining DOGE, Hassen spent nearly two decades as an executive at Basin Holdings, an enterprise involved in the manufacture, sale and servicing of oil rigs worldwide.
