The Congressional Research Service (CRS)

The Congressional Research Service (CRS) is the nonpartisan research arm of the U.S. Congress. Its mission: to provide lawmakers with authoritative, objective analysis on virtually every issue Congress faces — from climate to defense to taxes.

1. What CRS Does

CRS provides in-depth research, reports, and legal analysis directly to members and committees.

Translates complex policy issues into clear, factual briefings.
Prepares confidential memoranda for individual members.
Publishes public reports on hundreds of topics every year.

CRS is often called “Congress’s think tank.”

2. Where CRS Fits in Congress

CRS operates within the Library of Congress and supports both chambers equally.

It answers directly to congressional committees and members — not the executive branch.
Works closely with the Government Accountability Office (GAO) and CBO on oversight and analysis.

CRS is part of the legislative branch’s institutional knowledge base.

3. CRS Reports

Public CRS reports provide neutral, well-researched overviews of major policy issues.

Cover topics from cybersecurity to immigration law.
Often cited in hearings, press releases, and media coverage.
Available to the public via the Library of Congress website.

crsreports.congress.gov hosts thousands of searchable reports.

4. How Members Use CRS

Lawmakers rely on CRS experts for clarity, context, and constitutional grounding.

Members use CRS briefs to prepare for hearings or debates.
Committees request background papers before drafting legislation.
Staff rely on CRS data to ensure accuracy in bill language.

CRS ensures Congress legislates with knowledge, not guesswork.

5. Why It Matters

In an age of misinformation and polarization, CRS remains a model of factual rigor and neutrality.

When Congress seeks truth over talking points, it turns to CRS.
