He's the answer to a lot of trivia questions - A 3-time Presidential candidate who worked inside both the Nixon and Reagan administrations, Pat Buchanan was also a star back on the early days of cable news. In this episode of Greta Talk, Greta van Susteren sits  down with her old TV colleague for some frank talk about the Presidents he served, the medium he helped to define, and American politics now... and then. The conversation between the host of On the Record and the former host of Crossfire ranges from why he ran for President at all... to what's wrong with today's media. You may agree with them - and you may not. But you'll undoubtedly enjoy this meeting of two old friends.
