This legislative proposal aims to honor an individual by renaming a federal facility in their honor. Specifically, it designates the United States Postal Service building located at 417 West 7th Street in Columbia, Tennessee, with a new official name. The bill mandates that this facility will henceforth be known as the "Pharmacist's Mate First Class John Harlan Willis Post Office Building." Furthermore, it stipulates that all future references in any official document, map, or record of the United States to this facility shall be understood to mean the newly designated name. This action serves to commemorate the individual by permanently associating his name with a public service building.
