## FAQ
Where does the data come from? House Clerk and Senate public disclosures; a source link on every row. How fast? Filings are collected daily. Why amount ranges? Members disclose ranges, not exact amounts; we give low, high and midpoint. Scanned paper filings? Electronic filings are parsed today; scanned paper filings are listed with a link to the original.

Public-record data; not investment advice; no allegation of wrongdoing is made or implied about any member.
