Rep. Raul Ruiz (D-CA) serves on the House Committee on Energy and Commerce, which has jurisdiction over the Health Services sector. Health Services comprises 33.2% of his donor base ($2.18M), ranking third among Democratic members of Congress.

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.
