The nuclear option is a parliamentary procedure that allows the United States Senate to override a rule or precedent by a simple majority of 51 votes, instead of by a supermajority of 60 votes. The option is invoked by the presiding officer of the body ruling that the validity of a Senate rule or precedent is a constitutional question. The issue is immediately put to the full Senate, which decides by majority vote. The procedure thus allows the Senate to decide any issue by majority vote, regardless of existing procedural rules, such as current Senate rules specifying that ending a filibuster requires the consent of 60 senators (out of 100) for legislation, and 67 for amending a Senate rule. The term ''nuclear option'' is an analogy to nuclear weapons being the most extreme option in warfare.
