For more than 30 years, Ken Burns has been documenting the American experience. Films like “Jazz,” “Baseball” and “The Civil War” have for many become definitive accounts of chapters from our nation’s past. In 2009, he turned his lens on the history of our national parks, for a series that won two Emmys. In his most recent film, he tells the formerly untold story of an American couple who took on a life-threatening mission to combat the Nazis in Europe. This year, after decades of remaining mostly quiet on partisan politics, Burns also raised his voice in protest of now president-elect Trump. Ken Burns joins Diane to talk about politics, what keeps him curious, and why he says we urgently need civics back in U.S. schools.
