Interior Secretary Ryan Zinke resigned while under at least 18 federal investigations for corruption, conflicts of interest, and ethics violations. Scandals included: involvement in a Montana land deal benefiting himself and Halliburton chairman, using wildfire funds for personal travel, chartered flights costing $139,000, reassigning employees who disagreed with him, meetings with donors during official travel, and his wife using government vehicles. Zinke oversaw the largest reduction of protected federal lands in U.S. history, shrinking Bears Ears and Grand Staircase- Escalante monuments to open them for mining and drilling.
