Deep Throat
In 2000 Leonard Garment incorrectly identified Sears as Deep Throat in his book "In Search of Deep Throat". Sears then requested that Bob Woodward and Carl Bernstein (who unmasked Watergate with the help of Deep Throat) publicly deny it was him, and Bernstein complied. (Later it was revealed by Woodward that W. Mark Felt, former Deputy FBI Director was "Deep Throat".)
