A $5,800 whisky bottle Japan gave to Mike Pompeo is missing. The State Department is looking for it.

A bottle of whisky has gone missing, and the State Department is investigating. This is not your grandfather’s bottle of Jameson. It is a $5,800 bottle of Japanese whisky the Japanese government gave to then-Secretary of State Mike Pompeo in 2019, according to a filing in the federal register made public this week, and it’s quickly become a high-profile whodunit. Japan presented the bottle on June 24, 2019, the filing reported. Pompeo was in Saudi Arabia on an official visit at the time, so it is unknown whether the former secretary ever received the bottle himself. Pompeo visited Japan later that week for the Group of 20 summit. “Mr. Pompeo has no recollection of receiving the bottle of whisky and does not have any knowledge of what happened to it. He is also unaware of any inquiry into its whereabouts. He has no idea what the disposition was of this bottle of whisky,” William A. Burck, his lawyer, wrote in an emailed statement.

It is illegal for U.S. officials to accept such gifts from foreign governments above a certain dollar amount — $390, at the time Japan gave the whisky. Still, world leaders and diplomats often present tokens of appreciation to the president or top diplomats. “Non-acceptance would cause embarrassment to donor and U.S. Government,” the filing disclosing gifts to federal employees from foreign governments in 2019 notes, so the items are accepted and become the property of the federal government. On the list that year: a ceramic dragon head presented to President Donald Trump by the president of Vietnam, a Brazilian hardwood bench carved to resemble a jaguar (from Brazilian President Jair Bolsonaro, also to Trump) and an abridged first-edition copy of “The Second World War” by Winston Churchill, given to Trump by Queen Elizabeth II. All of those items were turned over to the National Archives. But the location of the Japanese whisky is listed as “Unknown.” “The Department is looking into the matter and has an ongoing inquiry,” a footnote reads. The filing did not offer additional detail about when and how the disappearance was discovered. The State Department did not immediately respond to emailed questions about the progress of the inquiry.
