The debate continued till February 2, Senators Guthrie, Hendricks, and Cowan opposing the bill and Trumbull, Fessenden, and Wilson supporting it. The vote was then taken and resulted, yeas 33, nays 12, absent 5. It went to the House, where it encountered unexpected opposition from Bingham, of Ohio, a radical Republican, who said:

Now what does this bill propose? To reform the whole civil and criminal code of every State Government by declaring that there shall be no discrimination between citizens on account of race or color in civil rights, or in the penalties prescribed by their laws. I humbly bow before the majesty of justice, as I bow before the majesty of that God whose attribute it is, and therefore declare that there should be no such inequality or discrimination even in the penalties for crime, but what power have you to correct it? That is the question. You further say that in the courts of justice of the several states there shall, as to the qualifications of witnesses, be no discrimination on account of race or color. I agree that as to persons who appreciate the obligation of an oath—and no others should be permitted to testify—there should be no such discrimination. But whence do you derive power to cure it by congressional enactment? There should be no discrimination among citizens of the United States, in the several states, of like sex, age, and condition, in regard to the franchises of office. But such a discrimination does exist in nearly every state. How do you propose to cure all this? By a congressional enactment? How? Not by saying in so many words (which would be the bold and direct way of meeting this issue) that every discrimination of this kind, whether existing in state constitution or state law, is hereby abolished. You propose to make it a penal offence for the judges of the states to obey the constitution and laws of their states, and for their obedience thereto to punish them by fine and imprisonment as felons. I deny your power to do this. You cannot make an official act done under color of law and without criminal intent and from a sense of duty, a crime.[90]

The only Republican member of the House, from the non-slaveholding states, who sided with Bingham, was Raymond, of New York. The House passed the bill by yeas 111, nays 38.

On the 27th of March, the President returned the bill to the Senate without his approval. He vetoed it on grounds of inexpediency and unconstitutionality. His arguments were substantially the same as those of Senators Saulsbury and Cowan.

Trumbull replied to the veto message in a speech of great power which occupies five pages of the Congressional Globe. He took up and answered the President's objections seriatim. These details need not now be repeated. There was one of a personal character, however, which calls for notice. He said that he had endeavored to meet the President's wishes in the preparation of both the bills, and had called upon him twice and had given him copies of them before they were introduced and asked his coöperation in order to make them satisfactory. In short, he had done everything possible to avoid a conflict between the executive and legislative branches of the Government, and since he had been assured that the President's aims, like his own, were in the direction of peace and concord, he was amazed when they were vetoed. At the conclusion of his speech he referred briefly to the constitutional objection to the bill saying:

If the bill now before us, which goes no further than to secure civil rights to the freedmen, cannot be passed, then the constitutional amendment proclaiming freedom to all the inhabitants of the land is a cheat and a delusion.

The floor and galleries of the Senate Chamber were crowded during the delivery of the speech and the roll-call followed immediately, resulting: yeas 33, nays 15, more than two thirds. The closing scene was thus described in a Washington letter to the Nation, April 12:

After three days of extremely ardent debate signalized by a speech of singular cogency and power from Senator Trumbull, the father of the bill, the vote was reached about 7 o'clock on Friday evening. When the end of the roll was reached and Vice-President Foster announced the result, nearly the whole Senate and auditory were carried off their feet and joined in a tumultuous outburst of cheering such as was never heard within those walls before.
