Sources: the House Clerk's financial disclosure PDFs and the Senate's eFD reports, read as filed. Amounts are the ranges on the form. "Late" compares the filer's trade and notification dates and the Clerk's filing date with the STOCK Act's deadlines (30 days after notification, never more than 45 days after the trade) and is not a finding by either chamber's ethics committee. A trade a later amendment corrected or deleted is counted once, as amended. A ticker is shown only when the filer wrote one. House filing index.
