Treasury Secretary Steve Mnuchin's flights on military aircraft on seven separate occasions since March cost taxpayers more than $800,000, the Treasury Department's Office of the Inspector General revealed Thursday.
Included in this series of flights was a $15,000 round-trip flight to New York to meet with President Trump at Trump Tower, the inspector general's report said. Additionally, Mnuchin took a flight in June to Miami to meet with the Mexican finance minister at a cost of $43,725.50.
The inspector general first began investigating Mnuchin's travel after Mnuchin took a trip to Kentucky in August to determine if he used the trip to capture an optimal view of the solar eclipse with his wife, Louise Linton.
However, Mnuchin's office dismissed claims the trip was connected to the eclipse and said he worked in the viewing around official business, which was confirmed by the report.
Mnuchin also asked to use a government jet for his honeymoon with his wife to travel to Scotland, France, and Italy the beginning of the summer, prompting some interest from the inspector general and consequently opening an official inquiry.
The request for a U.S. Air Force jet was put into writing by Mnuchin's office but was dismissed by Treasury Department officials as unnecessary upon looking into the situation. Estimates say it could cost $25,000 per hour to operate the jet, an Air Force spokesman said, according to ABC News.
Although the use of military aircraft departs from prior administrations, the report found nothing illegal about Mnuchin's actions.
"We appreciate the inspector general's thorough review of Treasury's travel requests, which identified no violation of law, regulation or ethics requirements in connection with the department's requests," a Treasury Department spokeswoman said, according to the New York Times.
Former Health and Human Services Secretary Tom Price resigned last week after it was revealed he traveled on private and military aircraft that cost taxpayers nearly $1 million.
Price was just one of several Cabinet officials facing scrutiny over their use of private or military aircraft to travel instead of commercial flights, a list which also includes Environmental Protection Agency Administrator Scott Pruitt, Interior Secretary Ryan Zinke, and Energy Secretary Rick Perry.
