This table shows current committee assignments only, from the legislators file. Earlier Congresses are listed below it, one source per Congress, and are not merged. Those sources are the legislators repo's own snapshots, and Stewart and Woon's dataset for the 103rd to 115th. Click a member's name to open their page.

Earlier Congresses: 16

Each Congress comes from one source, never merged: Stewart and Woon's assignment dataset (MIT) for the 103rd to the 115th; the legislators repo's own history for the 116th to the 118th. A Congress neither source covers is not shown. An older row whose committee code we could not map to this committee is not shown either; that does not mean the seat was empty.

Referral is the record's own routing, not a claim about attention, and a bill can sit before several committees. Sorted newest action first, with the 30 most recent here. By Congress: 119th (591), 118th (541), 117th (555), 116th (558), 115th (384), 114th (309), 113th (243), 112th (218), 111th (294), 110th (322), 109th (243), 108th (251).

These rows come from the covered-position field on LD-2 filings, matched to this committee only when the filed text names it together with its chamber; ambiguous text is left out. The field is self-reported and systematically underreported, so absence means a position was not disclosed, never that there is no government history. ‡ self-reported text

These are the agencies this committee authorizes, from our reviewed list; an agency missing here may not be listed yet. Contractors are each agency's largest recipients for the year, with USAspending's own figures, never summed here. The lobbying column counts filings whose client name matches the contractor's exactly, so other spellings are missed. This table as data. ‡ jurisdiction, not causation ‡ correlation, not purchase
