President Trump claims Congress approved the Arch a century ago. His administration points to a 1920s proposal as proof of historical intent.
The original plan called for a memorial in Washington. Whether that plan required congressional consent remains an open question.
Historians say the 1920s proposal differs from the current project. Its scope, location, and design were never fully defined.
The administration argues the Arch fulfills the “historic design intent” of that early proposal. Critics say the claim stretches the historical record.
Congress holds authority over federal monuments and public lands in the capital. Skipping that step would set a notable precedent.
Legal scholars note that past projects followed a formal approval process. No clear record shows lawmakers signed off on this design.
The debate centers on whether history supports the project or is being reinterpreted. Both sides cite the same era to make opposite points.
The outcome could reshape how future monuments move forward. It may also test the limits of executive authority over public space.
