A filibuster is a parliamentary procedure where debate over a proposed piece of legislation is extended, allowing one or more members to delay or entirely prevent a vote on the proposal.
A filibuster could be a lengthy speech or a series of speeches; or it could mean that the minority party agrees amongst its members to block a vote. The Senate reports the record for a verbal filibuster is about 24 hours in 1957 by Sen. J. Strom Thurmond, in opposition to the Civil Rights Act of 1957.
