Positions come from the unitedstates/congress-legislators roster, the Office of Government Ethics and the SEC’s Form 4 index. Every disclosed line names its own source and links the document the government published; we print what the filing says and never a price we did not read from it. Headlines and links come from the GDELT Global Knowledge Graph — the story stays with the publisher. The portrait, where we have one, is the public-domain Congressional Bioguide photograph.
