Politician trades

Ranges, not exact amounts. Politician data comes from official STOCK Act Periodic Transaction Reports, not 13F filings. The law requires a dollar range for each trade, not an exact amount, and reports can arrive up to 45 days after the trade (sometimes later). Any dollar total marked “est.” is an estimate built from range midpoints. House reports only: the Senate's disclosure site refuses automated access, so the trades shown here come from House reports — Senators may show no trades (or only trades from earlier House service), which is a gap in our source, not evidence that a Senator doesn't trade.
