12,779 lobbyistsConfirmed from the official record
Every lobbyist named in the lobbying reports we hold, by name. Each page lists the lobbyist's firms, clients, the bills named in reports that list them, and any earlier government job a report discloses.
A lobbying report names the houses of Congress and the agencies the lobbyists contacted. It does not say which members or staff they met.

Where this comes from
Lobbying Disclosure Act reports (LD-2), LDA.gov. We save our own copy of each page of LDA.gov's list of reports before we read it. These pages were built from our copies on .
2026-Q2: every page of LDA.gov's list saved and read.
A lobbying report states the registrant's income from the client (a lobbying firm) or its own lobbying expenses (an organization lobbying for itself), for the whole quarter and every issue together. A report of less than $5,000, or of no lobbying activity, states no figure. It is not the amount spent on one bill.
Senate Office of Public Records cannot vouch for the data or analyses derived from these data after the data have been retrieved from LDA.gov.
