This informative CRS report, in discussing recent salaries adjustments and denials, also provides a handy listing of what Congressional pay has looked like over the course of 200+ years. Another CRS report of value is the Salaries of Members of Congress: Congressional Votes 1990-2010. These two reports cover the salaries of Congress but do not discuss other appropriations given to each member; for that, you need to peruse Congressional Salaries and Allowances (again from CRS). In this document, gentle reader, you will find that each Representataive is given an average allowance of $1.5 million for district office staffing and the like, while Senators are alloted an average of $3.34 million. You can see the amount of money paid to staff by visiting this site from Legistorm; a history on Congressional staffing can be found here. You can also visit the Statement of Disbursements from the House of Representatives which is available within 60 days of the end of each calendar quarterly.
