A filibuster is a type of parliamentary procedure where debate is extended, allowing one or more members to delay or entirely prevent a vote on a given proposal. It is sometimes referred to as talking out a bill, and characterized as a form of obstruction in a legislature or other decision-making body.
Since the filibuster is a legislative tool used by the minority party (Democrat or Republican) to avoid being steamrollered by the majority, members of the minority (in this case, Senate Republicans) have a vested interest in opposing reforms that would make it more difficult to mount filibusters.
