MR. PRESIDENT,--There is just the point. The Senator says the question is not here,--in other words, that this is not the time to discuss the President. He is mistaken; this is the very time. The question is here at the instance of the Senator from Ohio, who gravely moves that we leave our seats, and from this time forward till December abdicate our constitutional guardianship of the public interests. To such a proposition there is but one natural and logical reply. It is, that we must not abdicate, so long as Andrew Johnson is in the Executive chair. If he continues President, we must remain at our posts, precisely as Grant remained before Richmond. Sir, if another person wielded the Executive powers of the nation, if there was anybody in that high office mindful of the National Constitution as interpreted by the Declaration of Independence, and disposed to carry forward the Acts of Congress adopted by such triumphant majorities, then I could vote with Senators to go home. Unhappily, it is not so. Anything but this. Our President is a public enemy, successor in spirit and opinion of Jefferson Davis, through whom the Rebellion is once more on its legs. Does any Senator, accustomed to vote with the Union party and to sustain the Union cause, question this simple statement of fact? Does he believe it overdrawn? Let him answer, if he does. Let him say where my language goes by a hair’s breadth beyond the exact truth. Here Mr. Sumner stopped for answer, and then proceeded. Because we have the successor of Jefferson Davis in the Presidential chair, therefore Congress must stay. That is my argument. A volume or oration could not add to the force of this simple statement. The more I think of this duty, the more commanding it seems. The President is the Executive; we are the Legislative. His influence is great; but ours is greater. If we choose to say so, we can be masters. We can apply the corrective to his mischief. Surely here is a motive. Ten States are now exposed to his malign influence, all of which may be arrested by our presence here. Let it be known that we are to continue in our seats, and every Union man throughout the Rebel States will feel stronger. He will be conscious at once of a panoply, which the President, and the Rebel tail, of which he is the head, cannot penetrate.
