"Beginning in 1970 and until the passage of P.L. 115-244, former Speakers of the House of Representatives were provided with an allowance upon their departure from the House. The statutorily authorized allowance has been available to former Speakers for office space and furnishings, office operations, franked mail, and staff assistance. Use of the allowance was limited to five years, beginning the day of expiration of a Speaker's tenure as a Representative, and was to be used solely for the administration and conclusion of matters relating to service as a Representative and Speaker of the House.The legislative branch appropriations act for FY2019 was enacted on September 21, 2018, and included a provision to repeal the allowance. The repeal of allowances applies to any Member who served in the 115th Congress or any succeeding Congress."
