Invoking Cloture in the Senate

Prepared for Members and Committees of Congress

loture is the only procedure by which the Senate can vote to set an end to a debate without
also rejecting the bill, amendment, conference report, motion, or other matter it has been 1
debating. A Senator can make a nondebatable motion to table an amendment, and if a C

majority of the Senate votes for that motion, the effect is to reject the amendment. Thus, the
motion to table cannot be used to conclude a debate when Senators still wish to speak and to
enable the Senate to vote for the proposal it is considering. Only the cloture provisions of Rule
XXII achieve this purpose.
There are several stages to the process of invoking cloture.
• First, at least 16 Senators sign a cloture motion (also called a cloture petition)
that states: “We, the undersigned Senators, in accordance with the provisions of
Rule XXII of the Standing Rules of the Senate, hereby move to bring to a close
the debate upon [the matter in question].”
• To present a cloture motion, a Senator may interrupt another Senator who is
speaking. When the motion is presented, the clerk reads it.
• The cloture motion then lies over until the second calendar day on which the
Senate is in session. For example, if the motion is filed on Monday, it lies over
until Wednesday, assuming the Senate is in session daily. If the motion is filed on
Friday, it lies over until Tuesday unless the Senate was in session on Saturday or
• The Senate votes on the cloture motion one hour after it convenes on the second
calendar day after the cloture motion was filed, and after a quorum call has
established the presence of a quorum. The time for the cloture vote may be
changed by unanimous consent, and the required quorum call is routinely
• The presiding officer presents the cloture motion to the Senate for a rollcall vote
at the time required by Rule XXII, even if the Senate had been considering other
business between the time the cloture motion was filed and the time for voting on
the motion arrives.
• The majority required to invoke cloture is three-fifths of the Senators duly chosen
and sworn, or 60 votes if there are no vacancies in the Senate’s membership.
However, invoking cloture on a measure or motion to amend the Senate’s rules
requires the votes of two-thirds of the Senators present and voting, or 67 votes if
all 100 Senators vote.
Senators who wish to offer amendments to a bill or amendment on which cloture has been
invoked must submit their amendments in writing before the cloture vote takes place. First-degree
amendments (which propose to change the text of a bill or a committee amendment in the nature
of a substitute) must be submitted in writing to the journal clerk when the Senate is in session, but
no later than 1:00 p.m. on the day after the cloture motion is filed. Second-degree amendments
(which propose to amend first-degree amendments) must be submitted at least an hour before the
Senate votes on cloture.

Cloture may be invoked only on a matter that is pending before the Senate or on the unfinished
business. It is not in order, except by unanimous consent, to invoke cloture on a bill before the
Senate has agreed to consider it. On the other hand, there is no limit on the number of times that
the Senate can vote on motions to invoke cloture on a bill, amendment, or other matter it is
If an amendment has been offered to a bill, the Senate may invoke cloture either on the bill or on
the amendment. Sometimes Senators prefer to invoke cloture on an amendment instead of a bill
because after the Senate invokes cloture, it may consider only amendments that are germane. This
germaneness requirement applies to amendments that are pending at the time that cloture is
invoked as well as to amendments that Senators offer after the Senate has voted for cloture. Thus,
if the Senate invokes cloture on a bill, the presiding officer immediately rules on whether any
pending amendment is germane. If the amendment is not germane, it is not eligible for further
If the Senators who wish to expedite passage of a bill also support a pending amendment to the
bill, they cannot invoke cloture on the bill without also killing the amendment they support. Their
alternative is to ask the Senate to invoke cloture on the amendment, not on the bill. Doing so
protects the amendment from becoming subject to the germaneness requirement. After the Senate
agrees to the amendment, however, it may be necessary for the Senate to invoke cloture a second
time, on the bill as amended.
