Page "L. Patrick Gray" Paragraph 59

Gray goes on to point out that at the time of this lunch the Attorney General was Richard Kleindienst, who was never implicated in any of the Watergate scandals.

Even if Smith meant that he was talking about John Mitchell, the former Attorney General, Gray further points out that no one ( outside of the conspirators ) knew of Mitchell's involvement until the following April, when John Dean admitted as much to special prosecutors.
