The Committee on Ways and Means is the chief tax-writing committee in the House of Representatives. The Committee derives a large share of its jurisdiction from Article I, Section VII of the U.S. Constitution, which declares, “All Bills for raising Revenue shall originate in the House of Representatives.” The committee has jurisdiction over revenue and related issues such as tariffs, reciprocal trade agreements, and the bonded debt of the United States. It also oversees revenue-related aspects of the Social Security system, Medicare, and social services programs. source
Each member’s figures cover every trade they disclosed, not only trades touching this committee’s jurisdiction.
Seats are the current Congress’s roster from congress-legislators, refreshed with the pipeline. A member with no disclosed trades is listed with dashes.
“Late” counts trades filed more than 45 days after the trade — a reporting fact, not an allegation of wrongdoing.
