AP---W. Mark Felt, the former FBI second-in-command who revealed himself as "Deep Throat" 30 years after he tipped off reporters to the Watergate scandal that toppled a president, has died. He was 95. Mr. Felt died Thursday of congestive heart failure, said John D. O'Connor, a family friend who wrote the 2005 Vanity Fair article uncovering Felt's secret.

The shadowy central figure in the one of the most gripping political dramas of the 20th century, Felt insisted his alter ego be kept secret when he leaked damaging information about President Richard Nixon and his aides to the Washington Post.
