Every sitting member of the House and Senate, ranked by the measure you pick. Ranks count within the chamber filter: #1 in Senate is first among senators. Figures here are the ones each member's own page shows.
Methodology: Laws enacted
Each member's sponsored bills and joint resolutions in the 119th Congress so far that became law, split into substantive laws and ceremonial ones (namings, commemorations and awards, by the site's public bill-type rules; a law not yet typed is counted ceremonial when the effectiveness rule calls it commemorative). "In other laws" counts a member's stalled bills whose identical or similar text became law inside another bill, as the Congressional Research Service lists it; it is shown for context, not added to the laws. From congress.gov and GovInfo. Every sitting member is ranked, zero included.
