Ghost Army Congressional Gold Medal Act This bill directs the Speaker of the House of Representatives and the President pro tempore of the Senate to award a Congressional Gold Medal to the 23rd Headquarters Special Troops, known as the "Ghost Army," collectively, in recognition of its service during World War II. The bill expresses the sense of Congress that the Smithsonian Institution should make the medal available for display elsewhere, particularly at appropriate locations associated with the Ghost Army, and that preference should be given to locations affiliated with the Smithsonian.
