"The Last of the President's Men" is a new book by Bob Woodward

The reporting done by Bob Woodward and Carl Bernstein tracking the Watergate break in and subsequent cover up helped take down President Richard Nixon.

But, there’s more to the story than what the Washington Post reporters wrote about in their best-seller, "All The President’s Men." Now, Woodward wrote about the man who revealed the existence of the secret taping system in the Oval Office: Alexander Butterfield, in "The Last of the President’s Men."

Butterfield was an aide to Nixon and was instrumental in getting the taping system put into place. When he left the White House, he took boxes and boxes of documents with him. Woodward spoke about his new book.
