"[L]et the President answer the interrogatories I proposed, as before mentioned, or some other similar ones. Let him answer fully, fairly, and candidly. Let him answer with facts and not with arguments. . . . But if he can not or will not do this, -- if on any pretense or no pretense he shall refuse or omit it -- then I shall be fully convinced of what I more than suspect already -- that he is deeply conscious of being in the wrong; that he feels the blood of this war, like the blood of Abel, is crying to Heaven against him."
