All process shall be served by the Sergeant-at-Arms of the Senate unless otherwise ordered by the court.

XXV.  If the Senate shall at any time fail to sit for the consideration of articles of impeachment on the day or hour fixed therefor, the Senate may by an order, to be adopted without debate, fix a day and hour for resuming such consideration.

On March 31 Rule VII was amended to read as follows: 

VII.  The Presiding Officer of the Senate shall direct all necessary preparations in the Senate Chamber, and the presiding officer on the trial shall direct all the forms of proceeding while the Senate are sitting for the purpose of trying an impeachment, and all forms during the trial not otherwise specially provided for, and the presiding officer on the trial may rule all questions of evidence and incidental questions, which ruling shall stand as the judgment of the Senate, unless some member of the Senate shall ask that a formal vote be taken thereon, in which case it shall be submitted to the Senate for decision; or he may, at his option, in the first instance submit any such question to a vote of the members of the Senate.

On April 3 Rule VII was further amended by inserting at the end thereof the following: 

Upon all such questions the vote shall be without a division, unless the yeas and nays be demanded by one-fifth of the members present, when the same shall be taken.

On March 13 Rule XXIII was amended to read as follows: 

XXIII.  All the orders and decisions shall be made and had by yeas and nays, which shall be entered on the record, and without debate, subject, however, to the operation of Rule VII, except when the doors shall be closed for deliberation, and in that case no member shall speak more than once on one question, and for not more than ten minutes on an interlocutory question, and for not more than fifteen minutes on the final question, unless by consent of the Senate, to be had without debate; but a motion to adjourn may be decided without the yeas and nays, unless they be demanded by one-fifth of the members present.
