Iran Nuclear Deal; 'The Daily Show with Jon Stewart'

President Obama's Iran nuclear deal is analyzed by Richard Haass, president of the Council on Foreign Relations, Chemi Shalev, editor at Haaretz, Jonathan Alter, columnist for the Daily Beast, and Mark Dubowitz, the executive director of the Foundation for Defense of Democrats. At the end of the 16-year run of "The Daily Show with Jon Stewart," we look back on past interviews with guests—including Jon Stewart, Stephen Colbert, and John Oliver—and discuss the show's significance with Dan Pfeiffer, formerly President Obama's senior advisor on strategy and communication, Ken Auletta, columnist for The New Yorker, Brooke Gladstone, host of WNYC's "On The Media," Dave Itzkoff, reporter for The New York Times, and Bill Carter, CNN contributor.
