"This report begins with an explanation of how to analyze committees' subpoena rules. The report then first surveys House committees' subpoena rules, followed by a survey of Senate committees' subpoena rules. Both surveys begin with a brief description of chamber rules, followed by a short summary of that chamber's committees' rules that are ancillary to committee subpoena authorization procedures or appear in only one or two committees' rules. The surveys each include a table that compares the chamber's committees' rules on authorizing and issuing subpoenas, with table notes adding further detail."
