Invoke cloture

Invoking cloture stops a filibuster. The two-step procedure begins with the filing of a petition for cloture signed by 16 Senators. A vote on cloture occurs two days after the petition is filed. A successful cloture vote occurs when 60 Senators vote to invoke cloture, thus cutting off the filibuster. Just as there is no limit to the number of filibusters on procedural motions or amendments to a bill, there is no limit to the number of times cloture can be invoked on a single piece of legislation.
