The purpose of this legislation is to officially name a specific post office in New York City after Jack Greenberg, honoring his contributions and legacy. Jack Greenberg was a notable civil rights attorney who played a significant role in advancing justice and equality. The key provision of this legislation is the designation of the United States Postal Service facility located at 114 John Street in New York, New York, as the "Jack Greenberg Post Office." This means that all official references to this post office in laws, maps, and other documents will now use this new name.
