NEW YORK (Reuters) - Mark Felt, the former FBI official who unmasked himself as the legendary "Deep Throat" source who leaked Watergate secrets, twice led FBI probes into finding Deep Throat, The Nation magazine said on Tuesday.
Combing through originally confidential FBI files now available to the public, co-writers David Corn and Jeff Goldberg found documents that showed Felt in charge of finding the source of Bob Woodward's and Carl Bernstein's Washington Post scoops that helped bring down President Richard Nixon.
