Cloture is the U.S. Senate’s only formal procedure for ending debate and forcing a vote on the matter in front of it. Under Senate Rule XXII, invoking cloture on a bill requires 60 of the 100 senators to vote yes, which is why breaking a filibuster is usually described as needing “60 votes.” On presidential nominations, the threshold is now a simple majority. Cloture does not decide whether the bill or nominee wins; it only shuts off debate so that a final vote can happen.
The Vote Thresholds
Rule XXII sets different bars depending on what the Senate is trying to end debate on.
For legislation, cloture requires three-fifths of all senators “duly chosen and sworn.” In a full Senate, that is 60 votes. The denominator is total membership, not just those present, so absences do not lower the target: 60 yes votes are needed whether every senator shows up or not.1GovInfo.

For nominations, the threshold is a simple majority. That change came in two steps. In November 2013, the Senate used a parliamentary maneuver known as the “nuclear option” to lower the cloture threshold to a simple majority for executive branch nominees and all federal judicial nominees except those to the Supreme Court, on a 52–48 vote. In April 2017, the Senate extended the same simple-majority precedent to Supreme Court nominees, clearing the way for the confirmation of Neil Gorsuch.2U.S. Senate.

One category still uses the old, higher bar: a proposal to change the Senate’s own rules requires a two-thirds vote of those present and voting. That is a large part of why the legislative filibuster has been so hard to eliminate through normal channels.2U.S. Senate. About Filibusters and Cloture | Historical Overview
How a Cloture Motion Is Filed and Voted On
The process starts when at least 16 senators sign a cloture motion and present it to the Senate. The motion does not come to an immediate vote. Rule XXII requires an intervening calendar day, so the vote happens one hour after the Senate convenes on the second calendar day after filing. A motion filed on Monday ripens for a vote on Wednesday, assuming the Senate meets both days.1GovInfo. United States Senate Manual, 110th Congress – Rule XXII Precedence of Motions
The delay is useful. It gives negotiators time to cut a deal while ensuring a backstop vote if talks fail. When the vote arrives, the presiding officer directs a roll call. A failed cloture vote does not kill the underlying bill; the majority leader can file another cloture motion and try again.
What Changes Once Cloture Is Invoked
Invoking cloture flips the Senate into a much more restrictive mode.
The biggest change is a hard cap on remaining debate. Legislation gets 30 hours of post-cloture consideration, and each individual senator is limited to no more than one hour of speaking time inside that window.1GovInfo. United States Senate Manual, 110th Congress – Rule XXII Precedence of Motions The 30 hours do not always run out. Post-cloture time technically cannot be yielded back, but if no senator seeks recognition to speak, the presiding officer will call for the vote early. The Senate can also skip straight to the final vote by unanimous consent.3Republican Policy Committee. Post-Cloture Rules and Precedents
For most nominations, the window is much shorter. In 2019, the Senate cut post-cloture debate on district court nominees and sub-cabinet executive branch nominees from 30 hours to two. Circuit court and Supreme Court nominees still get the full 30 hours.4Ballotpedia. The Federal Tap: Senate Changes Precedent to Limit Post-Cloture Debate on Most Presidential Nominees
Amendments After Cloture
Cloture also locks down what amendments the Senate can still consider. Only amendments submitted in writing before the cloture vote qualify, and even those must be germane to the underlying measure. No new amendments can be introduced, and anything the chair views as dilatory is automatically out of order.1GovInfo. United States Senate Manual, 110th Congress – Rule XXII Precedence of Motions The germaneness standard the Parliamentarian applies is narrow: amendments that limit or strike from the bill are allowed, while amendments that expand its scope or add new subject matter are ruled out.5Riddick Senate Procedure.

Why One Bill Can Face Several Cloture Votes
A single piece of legislation often needs cloture invoked on it more than once. A filibuster can block even the initial motion to bring a bill to the floor, so the majority leader may need to file cloture on that motion to proceed. Winning that vote only gets the bill onto the floor for debate. The minority can then filibuster the bill itself, requiring a second cloture vote on the underlying measure. In contested cases, the Senate may face three or more separate cloture votes before a bill reaches final passage.5Riddick Senate Procedure. Cloture Procedure
How Cloture Relates to the Filibuster
Cloture exists because of the filibuster. Any senator can, in principle, hold the floor and keep debate going, and cloture is the only formal way to make them stop. In the mid-1970s the Senate adopted a dual-tracking system that lets the chamber set aside a filibustered bill and work on other business while the cloture clock runs. Before dual tracking, a filibuster halted everything else the Senate wanted to do.
Dual tracking made filibusters cheaper for the minority. A senator no longer has to stand and talk for hours. The majority leader can note that 60 votes are not available, move on to other legislation, and file a cloture motion that ripens a couple of days later. That convenience is a big reason cloture filings have climbed so sharply over the decades.
When 60 Votes Are Not Required
Not every bill has to clear the 60-vote bar. The budget reconciliation process offers a path around the filibuster for legislation dealing with spending, revenue, and the federal debt limit. Bills moved under reconciliation cannot be filibustered and pass with a simple majority. That is how major tax and spending packages have cleared Congress when the majority party lacked 60 seats. The trade-off is that reconciliation comes with strict limits on what provisions can be included, and it can only be used a limited number of times per budget cycle.
For everything else, the 60-vote cloture threshold is the real vote requirement for passing legislation in the Senate. Bills that can attract 60 supporters will eventually reach a final vote; bills that cannot usually never see the floor at all. When a news report says a bill “doesn’t have the votes,” the reference is almost always to the 60 needed for cloture, not the 51 needed for final passage.
