Lobbying Disclosure Act (LDA)

Official site: https://lda.senate.gov

What This Site Is

This is the official U.S. Senate database for federal lobbying disclosures. It shows who is being paid to lobby the federal government, who they are lobbying for, what issues they are lobbying on, and how much money is involved — as required by law under the Lobbying Disclosure Act. Everything on this site comes from required filings submitted by lobbyists and organizations, updated on a quarterly schedule. This site tracks paid lobbying activity — not elections, not crimes, and not enforcement actions.

Common Things to Search For

  • A company or nonprofit name
  • A lobbying firm
  • An individual lobbyist
  • A specific policy area (defense, healthcare, energy, tech, etc.)
  • LD-1, LD-2, or LD-203 filings
  • Lobbying activity during a specific year or quarter

Good to Know

  • Lobbying disclosures are required by law, but they are not real-time
  • Most data is filed quarterly, so recent activity may not appear yet
  • Dollar figures are often ranges, not exact amounts
  • Lobbying disclosures are separate from campaign finance reports
  • Some searches work better using Registrant or Client ID numbers, not names
