Abe Lincoln's Deep Throat

Ralph E. Shaffer writes

... long before Watergate the nation was shocked by the startling publication of The Diary of a Public Man. Appearing in serial form in the North American Review, the published diary ran in four monthly installments in late 1879. Carrying the enticing subtitle "Unpublished Passages of the Secret History of the American Civil War," the series aroused partisans of all sorts - Republicans, Democrats, secessionists and unionists - as it recounted the fateful events leading to civil war.
