A time-delaying tactic in which a minority party Senator controls the floor and extends the debate of a measure in an effort to delay, modify or defeat a bill or amendment that probably would pass if it came to a direct vote. A filibuster can be stopped only by a 60-member vote of the senators present and voting. The House's stricter rules make filibusters more difficult, but other delaying tactics are occasionally employed using various procedural devices allowed by House rules.
