Lincoln gives William Kellogg advice on controversy Kellogg is having with Horace Greeley, N.Y. "Tribune" editor. "I think, if I were you, I would not pursue him further than necessary to my own justification. . . . Please excuse what I have said, in the way of unsolicited a[d]vice. I believe you will not doubt the sincerity of my friendship for you." Abraham Lincoln to William Kellogg, 11 December 1859, CW, 3:506-7.
