What the records do not show

Amounts are the ranges the filer chose on the form, not exact figures. A trade reported as between $1,001 and $15,000 could be either.
A transaction report says when the clerk received it, not when the order was placed, and a trade may have been made by a spouse, a dependent child, or an outside manager with no direction from the member.
Late means past the 45 days the STOCK Act allows. It is counted only from periodic transaction reports, never from annual-report holdings, and never from a trade dated before the member took office.
One record elsewhere shares this member's name and nothing else. A shared name is not a connection, and it is not cited here.
Some Senate rows carry no link to a public filing, so a few lines below point at no document.
Most companies in the database have no sector on file, so an overlap between a trade and a committee's jurisdiction is a floor, not a total.
