Committee rules exist under the umbrella of the rules that govern the entire House of Representatives. House and committee rules change every two years as the “new” House takes office after elections. The Congressional Research Service notes: “One of the majority party’s prerogatives is writing House rules and using its numbers to effect the chamber’s rules on the day a new House convenes.” That CRS report provides an overview of House rule changes from 2007 to 2017. CRS also provides a survey of House and Senate subpoena requirements through 2018. Finally, a CRS report describes rule changes affecting committee procedures in the current 116th Congress. Current committee rules are compiled in this 400 page document.
