Weiner quotes Nixon from a conversation when he was reacting to information I had learned on October 19, 1972, which unequivocally established that Mark Felt was leaking information. At one point, Nixon said to Haldeman, in Weiner’s (incorrect) version: “You know what I’d do with him [Felt]? Bastard!” In fact, what Nixon really said to Haldeman was much more telling, and interesting. He didn’t say “Bastard!” Rather, he said, “Ambassador.”
In short, Nixon would have done with Felt what he would later do with CIA director Richard Helms, to keep him happy and get him out of the way: make him an ambassador in a foreign land.
According to Dean, Weiner doesn't identify his sources for Watergate transcripts. NARA tapes specialist Samuel W. Rushay, Jr. writes that two scholars have made this particular error, one of whom is Stanley Kutler, who rushed out a book of transcripts in 1998. More about Kutler's errors here. Kutler also erred when transcribing a comment of Nixon's about the ranking Republican on the Senate Watergate committee, Howard Baker. One day in 1973, Nixon told his aides that Baker needed bucking up, one of his classic idioms. Kutler picked another consonant. Funny how these mistakes never make 37 look better.
