Watergate forever changed American politics, and in light of the revelations about the NSA's widespread surveillance program, the scandal has taken on new significance. Yet remarkably, four decades after Nixon was forced to resign, no one has told the full story of his involvement in Watergate. In The Nixon Defense, former White House Counsel John W. Dean, one of the last major surviving figures of Watergate, draws on his own transcripts of almost a thousand conversations, as well as documents in the archives to uncover what exactly Nixon knew and when he knew it.
