To codify Executive Order 14305 (relating to restoring American airspace sovereignty).

HR 4590 would codify Executive Order 14305 into permanent law, giving it the force of law rather than treating it as a temporary executive directive. This bill does not create new policy but formally enshrines the existing order’s provisions about "restoring American airspace sovereignty" into statute. It directly affects federal agencies like the Federal Aviation Administration, which must now implement these airspace sovereignty measures as binding legal requirements. The change ensures the order’s provisions will remain in effect without needing repeated presidential action.
