HOW WE ESTIMATE THIS
Estimated holdings start from the 2025 annual financial disclosure (each stock listed as a value range), rolled forward by trades disclosed since.
Everything is a range or estimate. The STOCK Act requires only broad dollar brackets (e.g. "$1,001–$15,000"), never exact amounts, share counts, or prices. Figures shown are midpoints.
"Filed after" is the gap between the trade and its disclosure. Over 45 days (⚠) is outside the STOCK Act's filing window.
Source. U.S. House Clerk periodic transaction reports & annual financial disclosures (public record). Not real-time; profit/loss can't be computed from disclosures.
