On the 28th of May Mr. Pearce made a report from the Select Committee, which, after a brief statement of facts, says, that “the Senate, for a breach of its privileges, cannot arrest a member of the House of Representatives, and, _a fortiori_, cannot try and punish him”; that “that authority devolves solely upon the House of which he is a member”; and that “the Senate cannot proceed further than to make complaint to the House of Representatives of the assault committed by one of its members.” It was ordered that “a copy of this report, and the affidavits accompanying the same, be transmitted to the House of Representatives.” Nothing further was done in the Senate on this matter. In the House of Representatives, on the day after the assault, Hon. Lewis D. Campbell, of Ohio, moved a Select Committee of five “to investigate the subject, and to report the facts, with such resolutions in reference thereto as in their judgments may be proper and necessary for the vindication of the character of the House.” The resolution was adopted, and the following Committee was appointed by the Speaker: Lewis D. Campbell, of Ohio, John Allison, of Pennsylvania, Howell Cobb, of Georgia, Alfred B. Greenwood, of Arkansas, and Francis E. Spinner, of New York. Alexander C. M. Pennington, of New Jersey, was substituted for Mr. Allison. To this Committee were referred the proceedings of the Senate. * * * * * In the testimony taken and reported by the Committee will be found an authentic account of the assault. The Committee visited Mr. Sumner at his house. “HON. CHARLES SUMNER, being sworn, testified. “_Question_ (by Mr. Campbell). What do you know of the facts connected with the assault alleged to have been made upon you in the Senate Chamber by Hon. Mr. Brooks, of South Carolina, on Thursday, May 22, 1856? “_Answer._ I attended the Senate as usual on Thursday, the 22d of May. After some formal business, a message was received from the House of Representatives, announcing the death of a member of that body from Missouri. This was followed by a brief tribute to the deceased from Mr. Geyer, of Missouri, when, according to usage, and out of respect to the deceased, the Senate adjourned. “Instead of leaving the Chamber with the rest on the adjournment, I continued in my seat, occupied with my pen. While thus intent, in order to be in season for the mail, which was soon to close, I was approached by several persons who desired to speak with me; but I answered them promptly and briefly, excusing myself, for the reason that I was much engaged. When the last of these left me, I drew my arm-chair close to my desk, and, with my legs under the desk, continued writing. My attention at this time was so entirely withdrawn from all other objects, that, though there must have been many persons on the floor of the Senate, I saw nobody.
