What is a filibuster used for in the legislative process?

A filibuster is a parliamentary procedure that allows one or more members of the legislative body to delay or prevent a vote on a bill by extending debate on the proposed legislation. It is often used in the U.S. Senate, where senators can speak for an extended period, sometimes for hours, to draw out the process. This tactic can serve various purposes, such as forcing further discussion on the bill or pressuring the majority to negotiate changes.

The filibuster's primary function is to slow down or block legislation that some senators are opposed to, creating an opportunity for additional discussion and possibly persuading others to reconsider their positions. While the process can lead to more thorough examination of the issues at hand, it is primarily recognized for its ability to delay action on legislation significantly.
