At Mr. Pompeo’s urging, President Donald J. Trump fired an inspector general who was investigating whether Mr. Pompeo and his wife misused government resources. The State Department’s new inspector general released a report in April saying Mr. Pompeo had violated ethics rules when he and his wife asked staff members to do personal tasks like taking care of their dog.
Stanley M. Brand, a criminal defense lawyer, ethics expert and former top lawyer for the House of Representatives, said that in his four decades working in Washington, he could not recall an instance in which legitimate questions had arisen about whether an official improperly took a gift from a foreign country.
“Like a lot of what occurred in the Trump era, this arises from a mix of rules and regulations that were previously obscure and rarely invoked,” Mr. Brand said. “I have been doing ethics stuff for 40 years and this has never been on the top of the list or on the list of problems.”
It was unclear what kind of whiskey the Japanese gave to Mr. Pompeo.
Most Japanese whiskeys taste similar to those made in Ireland, Scotland or the United States. But prices for aged Japanese whiskeys have risen drastically in recent years into the thousands or even tens of thousands of dollars.
The increase has been attributed to demand for Japanese whiskeys, said Stefan van Eycken, the author of the 2017 book “Whisky Rising” about Japanese whiskey. Demand fell off significantly in the 1980s, prompting a decrease in production, but picked up again around 2008, increasing the value of Japanese whiskey, particularly decades-old varieties.
“There is enormous demand from well-heeled collectors (especially in Asia) who will gladly pay the equivalent of a nice sports car for a single bottle of really old Japanese whiskey,” he wrote in an email.
