In a Los Angeles Times piece, former Nixon counsel John Dean writes that Bob Woodward "has advised his executive editor at the Washington Post that Deep Throat is ill. And Ben Bradlee, former executive editor of the Post and one of the few people to whom Woodward confided his source's identity, has publicly acknowledged that he has written Throat's obituary."
Previously, in Unmasking Deep Throat, Dean narrowed the speculation to four people who he thinks could be Woodward's secret source.
Update: Howard Kurtz says Executive Editor Len Downie "told me he had no information about Deep Throat being ill, not from Woodward or anyone else."
