This bill designates the United States Postal Service facility located at 29 Franklin Street in Petersburg, Virginia, as the "John Mercer Langston Post Office Building." The designation honors John Mercer Langston, a historical figure with significance to the Petersburg community. The bill, introduced by Senators Warner and Kaine in September 2024, is a naming measure that does not involve funding or establish specific timelines. Once enacted, all federal references to the postal facility would use its new official name. This type of legislation is ceremonial in nature and primarily affects how the federal government officially identifies and refers to the building in official documents and records.
