Sam Graves (R-MO) chairs the House Committee on Transportation and Infrastructure, which has jurisdiction over the Transportation sector. Transportation is his largest donor sector at 22.4% of contributions ($1.38M), ranking him #1 among Republicans in his chamber for donor concentration in his committee's jurisdiction.

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.
