Amends Rule XXII (Precedence of Motions) of the Standing Rules of the Senate to consider cloture of debate to have been invoked upon affirmative vote on the question of closing debate by three-fifths of Senators (two-thirds of those present and voting on a measure or motion to amend the Senate rules).
Makes it in order for the Majority Leader (or his or her designee), if the question on closing debate is decided in the affirmative by a majority of Senators voting but less than three-fifths of the Senators duly chosen and sworn (or less than two-thirds of the Senators voting, a quorum being present, in the case of a measure or motion to amend the Senate rules), to initiate a period of extended debate, to begin one hour later, upon the measure, motion, or other matter pending before the Senate, or the unfinished business, in relation to which the motion to close debate was offered.
Provides procedures applicable during such extended debate concerning: (1) the consideration of the measure, motion, or other pending matter, or the unfinished business, as the unfinished business to the exclusion of all other business; (2) the raising of a question about the presence of a quorum; (3) motions to adjourn or recess during such debate; (4) the number of times a Senator may speak; (5) postponement of a vote by the Majority Leader; and (6) the effects upon cloture if at any time no Senator seeks recognition.
