That year, the Senate adopted a rule to allow a two-thirds majority to end a filibuster, a procedure known as "cloture." In 1975 the Senate reduced the number of votes required for cloture from two-thirds of senators voting to three-fifths of all senators duly chosen and sworn, or 60 of the 100-member Senate.

Does a cloture end a debate?

Cloture (UK: US: /ˈkloʊtʃər/, also UK: /ˈkloʊtjʊər/), closure or, informally, a guillotine, is a motion or process in parliamentary procedure aimed at bringing debate to a quick end.

What does cloture invoked mean?

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 falls and is ineligible for further consideration.
