Source: U.S. House Clerk Periodic Transaction Reports (PTRs) filed under the STOCK Act. Disclosure can lag the actual trade by up to 45 days, so these are not real-time. Amounts are broad ranges as legally required — not exact figures. A transaction may belong to the member, their spouse, or a dependent child (see the owner column); a spouse or dependent trade is not the member's personal trade. This information is reused from the official public disclosure record for informational and public-interest (news) purposes only. Informational only — NOT financial advice, and NOT a signal to buy or sell.
