This bill amends title 40, United States Code, to authorize commercial filmmaking and photography on the United States Capitol Grounds, specifically excluding the Capitol Buildings. The Chief of the United States Capitol Police is empowered to issue permits for these activities, with a crucial stipulation that such activities can only take place when neither House of Congress is in session. The types of commercial activities deemed appropriate and the fees charged must be consistent with those previously allowed in Union Square before its jurisdictional transfer. Any fees collected will be used to cover costs incurred by the Architect of the Capitol and will be transferred to the Capitol Trust Account, with the Capitol Police Board responsible for promulgating regulations in consultation with House and Senate committees.
