Source: House Clerk PTRs and Senate eFD. Amounts are disclosed ranges; “2 ×” means two same-day lots, each in that range. “Filed” is the first report; a later amendment is noted under it and linked beside the filing. In House filings, owner “Self” includes trusts and accounts filed without an owner. Options are labelled as options, never as a purchase or sale of the stock.
