Members of Congress must file a Periodic Transaction Report (PTR) within 30 days of becoming aware of a securities trade, and no later than 45 days after the transaction. A sudden cluster of PTRs from the same member, or a spike across multiple members, is one of the earliest public signals that lawmakers acted on information ahead of the market. Data is pulled directly from disclosures-clerk.house.gov — the primary source — and cached for 6 hours.

Corporate / private jets that landed at DC-area airports. Auto-detected from adsb.fi live ADS-B; commercial airline traffic filtered out by callsign + registered owner. "Scheduled" = a hearing involves this company within ±48h. "Unscheduled" is the higher-signal row — jet on the ground, no public reason. The server must be running to log arrivals; this list grows over time.

Forward-looking schedule from api.congress.gov. Witness lists are linked PDFs — "Witness docs" column shows how many are attached, click "Details" for the full page. Cross-reference dates with the PTR table below: a hearing on Co. X + members of that committee filing PTRs near the same week is a real signal.
