Disclosures are drawn entirely from public STOCK Act and OGE Form 278-T filings; a conflict flag marks a trade in a sector the member's committee oversees (a signal to read, not a finding of wrongdoing). The average market-adjusted return is a descriptive summary of how these already-disclosed trades fared versus the market — it is not a prediction and not investment advice. Conflict screening compares trades only to the sectors a member's current committees oversee; members with no current committee seat (departed members, chamber leadership) aren't screened, so a 0 (or —) here is not an all-clear. See our methodology and data dictionary.

See how every flag is defined — and verify it against the original filings.
