Bob Woodward has done it again.�The Last of the President’s Men�exposes one of the final pieces of the Richard Nixon puzzle:

“Woodward reveals the untold story of Alexander Butterfield, the Nixon aide who disclosed the secret White House taping system that changed history and led to Nixon�s resignation. In forty-six hours of interviews with Butterfield, supported by thousands of documents, many of them original and not in the presidential archives and libraries, Woodward has uncovered new dimensions of Nixon�s secrets, obsessions and deceptions.”

In this edition of Greta Talk, Greta Van Susteren talks with Woodward in depth about Alexander Butterfield, Hillary Clinton’s email investigation, and how Nixon felt “untouchable” before the Watergate scandal came to light. Woodward and the On the Record host also remember Senator Fred Thompson, and even discuss why�Butterfield appeared before Watergate committees without a lawyer.
