Even in a Cabinet stocked with millionaires and billionaires, Ryan Zinke’s stewardship of the Interior Department has been distinguished by his monarchical flair. On his first day on the job, Zinke rode a horse to the office, where he quickly set about redecorating the place with a glass case display of knives. He reinstituted an arcane military ritual in which staffers are required to scurry up to the roof to fly a special secretarial flag whenever he enters the building. He commissioned commemorative coins bearing his name to give out to employees and visitors. His wife, Lolita Zinke, reportedly treats Interior Department staff like her personal party planners and travel agents. And, of course, like any good Trump administration official, there are the private flights on the taxpayers’ dime. Zinke has called public scrutiny of the $20,000 bill he racked up by refusing to fly commercial “complete and utter bullshit.” But, as Politico reports, private jets were hardly the only way Zinke avoided the line at the airport.

In one instance this summer, Zinke spent $8,000 on a helicopter to take him from the swearing-in of his congressional successor, Rep. Greg Gianforte, in Washington, D.C., to an emergency management exercise in West Virginia. By car, that trip would have taken two hours, but don’t ask the Interior Department staff about the decision to take a chopper instead. “The swearing in of the Congressman is absolutely an official event, as is emergency management training,” spokeswoman Heather Swift told Politico in an e-mail. “Shame on you for not respecting the office of a Member of Congress.”

In July, Zinke ordered a Park Police helicopter to whisk him to and from Yorktown, Virginia, so that he could get back to D.C. in time for a horseback ride with Vice President Mike Pence. In Yorktown, Zinke did a “walking tour” of a Revolutionary battlefield; a day before the trip, someone from his office threw in a 30-minute flyover of an area where an energy company is building high-voltage electric transmission lines over the James River. An Interior employee justified the trip to travel scheduler Tim Nigborowicz by noting that Zinke would be able to use the opportunity to kick the tires, saying, “the Secretary will be able to familiarize himself with the in-flight capabilities of an aircraft he is in charge of.”

In October, Zinke received a rare rebuke from the Interior’s Office of the Inspector General, which was trying to figure out if the secretary’s use of taxpayer-funded private jets was completely above board. The investigation had been made extremely difficult, if not impossible, according to Deputy Inspector General Mary Kendall, due to “absent or incomplete documentation” for many of the trips in question. According to Kendall, Interior officials had failed to provide evidence to “distinguish between personal, political, and official travel” or cost-analysis documentation that could justify Zinke’s decision to fly on chartered or military aircraft. The department responded by saying, essentially, that it was Barack Obama’s fault for leaving “an organizational and operational mess” behind—an excuse it’ll presumably use again should there be any question about Zinke’s helicopter habit.
