filibuster

A filibuster is a parliamentary procedure where one or more members of a legislature debate over a proposed piece of legislation to delay or entirely prevent a decision being made on the proposal. It is sometimes referred to as "talking a bill to death" or "talking out a bill" and is characterized as a form of obstruction in a legislature or other decision-making body.
This form of political obstruction reaches as far back as Ancient Roman times and could also be referred to synonymously with political stonewalling. Due to the often extreme length of time required for a successful filibuster, many speakers stray off-topic after exhausting the original subject matter. US Senators have, for example, read through laws from different states and recited past speeches and recipes.
