The next offer of testimony to be rejected was No. 23--Mr. Gideon Welles, Secretary of the Navy, on the stand, to prove that the Cabinet had advised the President to veto the Tenure-of-Office Bill as unconstitutional. The Chief Justice ruled the testimony admissible for the purpose of showing the intent with which the President had acted in the transaction. Prosecution objected, and by a vote of 20 to 29, the decision of the Chief Justice was overruled. No answer to this interrogatory was permitted, every vote to refuse this testimony being cast by a Republican, every one of whom, at the close of the trial, voting to convict and remove Mr. Johnson for alleged violation of a law which he believed to be unconstitutional--which he was advised by the head of the Law Department of the Government was unconstitutional and therefore not a law which he had sworn to execute, and the constitutionality of which he had endeavored to get before the courts for adjudication--those 29 Republicans so voting after having refused to hear testimony in his defense on these identical points. The next disputed interrogatory was No. 24--that Mr. Johnson's Cabinet had advised him that the Secretaries who had been appointed by Mr. Lincoln and still holding, (Mr. Stanton, Mr. Seward, and Mr. Welles,) were removable by the President, notwithstanding the assumed restriction of the Tenure-of-Office Act. The Chief Justice ruled this testimony to be admissible. Objection was made by the Prosecution, and a vote taken, and the interrogatory was rejected--22 to 26--every nay vote being a Republican, every one of whom at the close of the trial, voting to convict and remove Mr. Johnson from office, after having refused to hear this very important testimony in his behalf. Defense next offered to prove (No. 25) that it was determined by the President, with the concurrence of the Cabinet, that an agreed case for the determination of the constitutionality of the Tenure-of-Office Act should be made. This testimony was objected to, and a vote taken, which was 19 to 30. Every one of the gentlemen voting to reject this testimony, Mr. Johnson's right to which cannot with any possible showing of fairness be successfully disputed, were Republicans, and after so voting, at the close of the trial, declared by their several verdicts that he had been fairly proven guilty of a high misdemeanor in office, by violation of the Tenure-of-Office Act in seeking a judicial determination of the validity of a disputed Act of Congress, and should be expelled from office.
