This legislation, named the "Statutory Term Limits on Congressional Pay and Power Act" , aims to impose significant restrictions on Members of Congress who have accumulated 12 or more years of service in either the House of Representatives or the Senate. The core purpose is to limit the influence and financial benefits of long-serving members. Specifically, after reaching 12 years of service, a Member would become ineligible for their congressional compensation. Furthermore, these Members would be prohibited from holding key leadership roles, including serving as a chair or ranking minority member of any standing or select committee. The bill also defines and restricts eligibility for various House or Senate leadership positions , such as Majority or Minority Leaders, Whips, and committee chairs. These new prohibitions are designed to take effect starting with the One Hundred Twenty-First Congress and for all subsequent Congresses. The bill is enacted under the rulemaking power of both the House and Senate, acknowledging each chamber's constitutional right to modify its own rules.
