Public-interest transparency data from official U.S. House Clerk STOCK Act disclosures (periodic transaction reports). Amounts are disclosed as ranges (e.g. $1,001–$15,000), not exact values, and members may report a trade up to 45 days after it happens — so recent activity can be missing. Trades flagged LATE were reported after 45 days. Scanned paper filings are linked but not parsed. Senate eFD ingest is not available yet.
