Rick Larsen (D-WA) is the ranking member of the House Committee on Transportation and Infrastructure, which has jurisdiction over the Transportation sector. Transportation comprises 19.3% of his donor base ($1.09M), ranking him #1 among Democrats in his party for donor concentration in 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.
