Rep. Rick Larsen (D-WA) serves as ranking member of the House Committee on Transportation and Infrastructure, which has jurisdiction over the Transportation sector. Transportation is his largest donor sector at 19.2% of contributions ($1.17M), ranking him #1 among House Democrats in donor concentration from that sector.

How we built this: a statistical pattern surfaced from public records — FEC campaign finance, Senate/House Lobbying Disclosure Act filings, and Congress.gov. The donor concentration and the legislative action are concurrent facts; this does not imply contributions caused the action, that the member acted improperly, or that the bill specifically benefits the named sector.
