Preserving Liu Xiaobo Legacy of Freedom & 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 Liu Xiaobo and collectively to all those who have peacefully advocated for democracy and human rights in China in recognition of their achievements and contributions to freedom, human rights, and peace in China and globally. The bill expresses the sense of Congress that the Smithsonian Institution should make the medal available for display, particularly at locations: (1) associated with the research of the Tiananmen Protests of 1989 and their violent suppression, and (2) dedicated to preserving the history of the Chinese pro-democracy movement.
