What is filibuster who can engage in filibuster?

A filibuster is a legislative tactic used in the U.S. Senate to delay or block a vote on a bill or nomination by extending debate on it. Senators can engage in a filibuster, often by delivering lengthy speeches or using procedural maneuvers to prevent the Senate from moving forward. It typically requires a supermajority of 60 votes to end a filibuster through a process called cloture. The tactic is often employed by the minority party to express opposition or push for amendments.
