Final answer:
Rule 22 was created in 1917 to allow the Senate to hold a cloture vote and end debate. This rule was introduced to address the filibuster tactic used by senators to delay or prevent a vote on a bill. Cloture requires a two-thirds majority and helps prevent the hijacking of the Senate floor.
Step-by-step explanation:
In 1917, the Senate passed Rule 22, which allowed the chamber to hold a cloture vote to end debate. This rule was implemented to address the filibuster tactic, where a senator would speak for long periods of time to prevent the Senate from closing debate and acting on a bill. Cloture requires a two-thirds majority, making it difficult to invoke, but it generally prevents senators from hijacking the floor.
