The same assurance of absolute fairness as that of Mr. Boutwell, was also given by Mr. Bingham, another of the Managers of the Prosecution on the part of the House, in his opening plea before the Senate: "It is," said he, "certainly very competent for the Senate, as it is competent for any court of justice in the trial of cases where questions of doubt arise, to HEAR THE EVIDENCE, and, where they themselves are the judges of both the law and the fact, to DISMISS SO MUCH OF IT AS THEY MAY FIND INCOMPETENT, if any of it be incompetent. * * * Under the Plea of Not Guilty, as provided in the rules, every conceivable defense that the accused party could make to the Articles here preferred, can be admitted."

Mr. Manager Butler also said, on the same occasion: "Upon this so great trial, I pray let us not belittle ourselves with the analyses of the common law courts, or the criminal courts, because nothing is so dangerous to mislead us."

These and other like assurances were given of the widest reasonable latitude in the reception of testimony in the trial then opening. There was thus every reason to expect that Mr. Johnson would have a fair trial. But no sooner had the Prosecution completed its examination of witnesses, in which but seven interrogatories had been objected to of the long list proffered by the Prosecution, than a different rule seemed to have been established for the treatment of proffered testimony, and a large mass of relevant and valuable testimony in behalf of the President was ruled out on objection of the Prosecution, as inadmissible, and, as a rule that, had very few exceptions, on partisan divisions of the Senate.
