Part 1: Oliver Stone Interviews Putin on U.S.-Russia Relations, 2016 Election, Snowden & NATO

The Senate is slated to vote today on whether to impose a spate of new sanctions against Russia over allegations of Russian meddling in the 2016 U.S. election. The vote comes only one day after the much-anticipated testimony of Attorney General Jeff Sessions before the Senate Intelligence Committee. For more, we speak to three-time Academy Award-winning filmmaker Oliver Stone about his new TV special, "The Putin Interviews," which is airing on Showtime this week. The series is based on more than 20 hours of interviews Stone conducted with Russian President Vladimir Putin over the past two years.
