congressional salaries
The 27th Amendment to the Constitution of the United States became the rule that restrained congressional salaries. Oddly, this was proposed by James Madison in 1789, but it was not finalized until 1992.
The document that addressed congressional pay raises is the Federal Payment and Flexibility Act of 2019. This act established the framework for annual cost-of-living adjustments for Members of Congress, which effectively determines their pay raises. The purpose of the document was to ensure transparency and accountability in the process of determining congressional salaries.
Each individual state legislature determines the districts.
the 27th amendment
The 27th amendment pertains to congressional salaries. This amendment states that any changes to salary cannot go into effect until the next election of representatives. This is to prevent congress from raising their own salaries.
The census determines how many Congressional Representatives we have for the next decade.
Members are likely to say almost anything and need protection
The US Congress sets all federal salaries including the President. (It can not reduce salaries of people already in office .)
