The main purpose of this legislation is to limit the time a Member of Congress can serve in leadership roles within committees. Specifically, it aims to prevent any Member from serving as the chair or ranking minority member of a committee after they have completed 12 years of cumulative service in either the House of Representatives or the Senate. Key provisions of the legislation include a clear restriction on Members of Congress who have served 12 or more years. Once they reach this threshold, they will no longer be eligible for certain benefits.
