Two offices hold the whole record
The Clerk of the House and the Secretary of the Senate are the twin custodians of federal lobbying disclosure — and that division of responsibility is less arbitrary than it looks.
Why Two Offices, Not One
Federal lobbying disclosure has no single agency of its own. When the Lobbying Disclosure Act took effect in 1996, Congress assigned the filing obligation to the two chambers it already knew how to administer: registrations and quarterly reports go simultaneously to the Clerk of the House of Representatives and to the Secretary of the Senate. The logic follows the Constitution's bicameral structure. The obligation does not depend on which chamber a lobbyist contacts: whether a registrant lobbies only House offices, only the Senate, or both, as most do, the filing goes to both the Clerk and the Secretary. In practice, the two offices coordinate so that a single electronic submission reaches both at once, but the legal obligation runs to each independently.
Neither office is a regulatory body in the ordinary sense. The Clerk's primary duties concern the internal workings of the House — recording votes, publishing the Congressional Record, managing administrative functions for members. The Secretary of the Senate holds an equivalent role on the other side of the Capitol. Lobbying disclosure was layered onto these existing functions, not built into a purpose-designed bureau. That history matters because it shapes what the offices can and cannot do: they receive, process and publish the filings, but enforcement — prosecuting false statements, referring suspected violations — runs through the Department of Justice and, for compliance review, through the Government Accountability Office ↗, which audits the system's compliance on a recurring basis.
What the Offices Actually Hold
Every registration and every quarterly report filed since the LDA took effect is part of this dual record. A registration identifies the lobbying firm or individual, the client, the general issue areas, and — where relevant — whether any of the lobbyists were formerly covered government officials, which triggers the revolving-door disclosures attached to each report. Quarterly reports then add income or expenditure figures (rounded to the nearest $10,000, with expense and income thresholds determining who must report), the specific bills or federal agencies contacted, and the chambers where activity occurred.
The offices make the raw filings available through the Senate's lobbying disclosure portal ↗, where bulk data downloads allow researchers and journalists to reconstruct the full history of any registrant or client. OpenSecrets — the public-facing name of the Center for Responsive Politics — draws substantially on this record to produce the aggregated spending figures that appear most often in news coverage. But the underlying source is always the dual submission to the Clerk and the Secretary. When a figure from OpenSecrets is cited, what it represents is a processed version of data that originated in those two offices.
The 2007 Honest Leadership and Open Government Act, passed in the aftermath of the Jack Abramoff conviction, shortened the reporting cycle from semi-annual to quarterly and added a requirement that the filing system be searchable online, accessible without charge, and updated within 48 hours of submission. That last requirement effectively forced the two offices to modernize their joint infrastructure, producing the searchable database that researchers use today. Before 2008, the filings existed on paper or in formats that were difficult to aggregate; the 2007 act turned a compliance archive into a functional public record.
The Limits of the Record
What the two offices hold is limited to what registrants are required to disclose. Contacts below the registration threshold — where an individual's lobbying activity does not meet the minimum time or income tests — generate no filing at all. Grassroots campaigns, which direct public pressure toward officials rather than contacting them directly, fall outside the definition entirely and appear nowhere in the Clerk's or Secretary's data. The record is therefore comprehensive within the legal definition of lobbying and silent about everything outside it. Understanding those edges is as important as knowing what the offices hold, because the gap between the two is where much of the influence machinery runs without generating a line of public data.
