Last night, C-SPAN 1 ran an August 29, 1976 edition of CBS' Face the Nation. The guest was Mark Felt, idenitified this past week as Deep Throat, the deep background source who confirmed Bob Woodward and his reporting partner, Carl Bernstein, were moving in the right direction as they investigated the criminality of the Nixon Administration related to the Watergate break-in, its cover-up, and undermining the Constitution.
