The U.S. Treasury Department’s watchdog has begun reviewing the circumstances of Secretary Steven Mnuchin’s trip to Kentucky with his wife last month, where he discussed tax plans at a public event and toured Fort Knox.

…“at times” Mnuchin used government aircraft to “facilitate his travel schedule” and to ensure he has access to secure communications, the spokesperson said.

…Past Treasury secretaries typically flew commercial airlines when they were available on domestic trips for official business, but occasionally used government aircraft when flying internationally.
