On Wednesday evening, September 12, Supreme Court Justice Clarence Thomas joined Constitutional Accountability Center board member and Yale law professor Akhil Amar on the stage of the National Archives’ William G. McGowan Theater, and riveted a packed house throughout an animated discussion of the past, present, and future of the Constitution. Entitled “The Constitution Turns 225,” the program, which was co-sponsored by the Archives, CAC, and the Federalist Society, was live-streamed on C-Span’s BookTV.org.
