David Corn is a veteran Washington journalist and political commentator. He is the Washington bureau chief for Mother Jones magazine and an analyst for MSNBC. He is the author of three New York Times best-sellers, including "Showdown: The Inside Story of How Obama Battled the GOP to Set Up the 2012 Election" and "Hubris: The Inside Story of Spin, Scandal, and the Selling of the Iraq War" (co-written with Michael Isikoff). He is also the author of the biography "Blond Ghost: Ted Shackley and the CIA's Crusades and the novel Deep Background." Corn's new book, also co-written by Michael Isikoff, is "Russian Roulette, The Inside Story of Putin's War On America and The Election of Donald Trump," which leaves little doubt Putin has made it into our Whitehouse.
