Members of Congress who trade $BIIB

About this data
Campaign finance figures are aggregated from public Federal Election Commission filings (public domain). Stock trades, lobbying, and contract figures are derived from disclosures compiled by QuiverQuant. Contributions are grouped by the donor's reported employer — they are not OpenSecrets industry clusters, and the totals combine individual contributions with affiliated PAC activity where reported.
Contributions and disclosures are not proof of influence. They show who gave and what was reported, not why a member voted a particular way. Amounts reflect the cycle or as-of dates noted beside each figure and may be revised as later filings are processed.
