Redesignating the Robert E. Lee Memorial in Arlington National Cemetery as the "Arlington House National Historic Site".

This bill redesignates the Robert E. Lee Memorial in Arlington National Cemetery as the "Arlington House National Historic Site," updating its official name to reflect the historic home's original identity. It requires all federal references in laws, documents, and maps to use the new name and repeals two prior resolutions that established the Lee memorial. The change directly affects federal records and the site's administrative designation under the National Park Service, without altering its location or public access. This is a procedural renaming focused on historical accuracy, not policy change.
