Document Introduction

This document is the official U.S. publication of the "Congressional Directory" for the 118th Congress (2023-2024). This directory is one of the oldest working manuals within the U.S. government, with its official version tradition dating back to the 30th Congress in 1847. This edition, guided by the Joint Committee on Printing and compiled by the Government Publishing Office, comprehensively covers the core organizational structure and contact information of the three branches of the U.S. government—legislative, executive, and judicial. It serves as an authoritative foundational reference tool for studying the American political system, conducting policy analysis, and making contacts.

The main body of the report first details the changes in membership after the formation of the 118th Congress, up to the date of the directory's publication. Senate changes include the resignation of Ben Sasse (Nebraska), the death of Dianne Feinstein (California), and the appointment and swearing-in dates of their successors. House changes record seat turnovers due to death, resignation (e.g., David Cicilline, Chris Stewart, George Santos), expulsion (George Santos), as well as corresponding special election results and successor swearing-in information. For background, the document also traces member changes following the previous (117th) Congress elections, including the appointment of Alex Padilla after Kamala Harris resigned to become Vice President, and the special elections for several House seats.

The core content systematically lists, by state and territory, the official biographical information for all members of the 118th Congress (Vice President, Senators, Representatives, Delegates, and Resident Commissioner). Each biography is based on information provided or authorized by the member's office, including place of birth, educational background, professional experience, military service (if applicable), awards, religious affiliation, family information, committee assignments, and election history. Following this are each member's office addresses and phone numbers in Washington D.C. and their districts, key staff (e.g., Chief of Staff, Legislative Director, Communications Director), and links to online resources. Simultaneously, the report provides population data for each congressional district based on the 2020 Census, lists of included counties/cities, and ZIP code ranges, supplemented by district maps for some states, clearly outlining the political geography at the federal level.

Beyond member information, the directory delves into the internal organizational structure of Congress. It fully lists the leadership of both chambers, party leadership committees, and the membership rosters of all standing committees, select committees, and intelligence committees. Furthermore, the document covers congressional support agencies (e.g., Congressional Budget Office, Government Accountability Office, Library of Congress), Capitol officials at various levels (e.g., Secretary of the Senate, Clerk of the House, Capitol Police), and member access to press galleries. The directory also expands its scope to the entire federal government, detailing the organizational structure and key contacts of the White House, all 15 executive departments (State, Treasury, Defense including military departments, Justice, etc.), major independent agencies, government corporations, quasi-official bodies, the federal court system, and even the District of Columbia government. Finally, the appendices provide long-term reference statistical information such as historical congressional election voting data, congressional session records, and changes in apportionment of congressional seats.

The value of this document lies in its official nature, comprehensiveness, and timeliness. It is not only a guide to the "infrastructure" of American political operations but also provides precise raw data for analyzing the evolution of congressional power structures, partisan strength comparisons, committee jurisdiction allocation, and executive-legislative branch interaction patterns. For defense and international political analysts, the information on the composition of committees such as Armed Services, Foreign Affairs, Intelligence, and those related to strategic competition (e.g., the Select Committee on the Strategic Competition Between the United States and the Chinese Communist Party) serves as the foundation for assessing U.S. national security and foreign policy legislative agendas and the positions of key figures.
