This report analyzes rules changes made on only the opening day of the 110th, 111th, 112th, 113th, and 114th Congresses, with references in footnotes to other selected legislation and actions during these Congresses that also affected House rules. 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. Because all Members of the House stand for election every two years, the Members-elect constitute a new House that must adopt rules at the convening of each Congress.

This report reprints the text of the five National Security Letter (NSL) statutes as they now appear and as they appeared prior to amendment by the USA PATRIOT Act (to which form they would be returned under S.1125 and H.R. 1805). NSLs are roughly comparable to administrative subpoenas. Various intelligence agencies use them to demand certain customer information from communications providers, financial institutions, and consumer credit reporting agencies under the Right to Financial Privacy Act, the Fair Credit Reporting Act, the National Security Act, and the Electronic Communications Privacy Act.
