Section is based on the three provisos in paragraph under heading “Expense Allowances of the Vice President, Majority and Minority Leaders and Majority and Minority Whips” in the appropriation for the Senate in the Supplemental Appropriations Act, 1977 (Pub. L. 95–26), and section 109 of the Congressional Operations Appropriation Act, 1978, which is title I of the Legislative Branch Appropriation Act, 1978 (Pub. L. 95–94), and subsequent acts cited in the credits to this section.

2004—Pub. L. 108–447 substituted “$40,000” for “$20,000”.

2003—Pub. L. 108–7 substituted “$20,000” for “$10,000” and “not exceed $10,000” for “not exceed $5,000”.

1986—Pub. L. 99–514 substituted “Internal Revenue Code of 1986” for “Internal Revenue Code of 1954”, which for purposes of codification was translated as “title 26” thus requiring no change in text.

1983—Pub. L. 98–63 substituted provisions increasing allowances for each Whip to $5,000 each fiscal year, effective fiscal year 1983 and each fiscal year thereafter, for provisions authorizing not to exceed $2,500 each fiscal year for each Whip, effective Apr. 1, 1977.

1978—Pub. L. 95–355 substituted provisions increasing allowances for each leader to $10,000 each fiscal year, effective fiscal year 1978 and each fiscal year thereafter, for provisions authorizing not to exceed $5,000 each fiscal year for each leader, effective with fiscal year 1977 and each fiscal year thereafter.
