James Kwon, maritime director for the Port of Oakland in California, claimed four years ago to treating clients to drinks and dinner at a place called D Houston Inc.
The expenses added up to $4,537.
However, it was recently discovered by the Port of Oakland that 'D Houston Inc' is the corporate name for Treasures - a strip club in Houston, Texas.
The Port of Oakland stated: "The nature of the venue is not evident from the receipt.
"The Board of Port Commissioners takes this matter very seriously and will take whatever action is required to improve our financial oversight to ensure expenditures like this don't occur in the future."
