Filibusters Block Senate Action with Lengthy Debates 2 Longest Filibusters in Senate History Analysis Filibuster is an informal term for any attempt to block or delay Senate action on a bill or other matter by debating it at length, by offering numerous procedural motions, or by any other delaying or obstructive actions In 1842 the House placed a time limit on all debate, making the filibuster primarily a Senate tool Source: Al Kamen, “Filibusters ain’t what they used to be,” Washington Post, In the Loop Blog, March 6, Alfonse D’Amato (R-N.Y.)

Senate Invokes Cloture to Halt Filibusters Source: 4 Senator files a motion for cloture Signed by 16 senators? No: Motion for cloture fails and is not taken to vote Yes: Motion for cloture is taken to vote Voted for by at least 60 senators? Yes: Cloture invoked and filibuster is blocked No: Cloture fails Analysis Cloture, established by U.S. Senate Standing Rule XXII, is the Senate’s only procedure to place a time limit (30 hours) on debate over a bill, by which it may stop a filibuster In 1975, the Senate reduced the number of votes necessary to invoke cloture from two-thirds to three-fifths In November 2013, the Senate changed cloture rules as they apply to votes to confirm most judicial and executive branch nominees Source: U.S. Senate Reference, 2013; Richard S.
