What the Constitution Lobbying Data Shows
Under Senate Lobbying Disclosure Act code CON, 68 organizations reported federal lobbying activity on Constitution across the 2023-2024 reporting period, with combined expenditures of $6.3M. That volume of filings places Constitution among the issues where corporate, trade-association, and advocacy lobbying is actively shaping the legislative and regulatory agenda, with each registrant required to disclose specific bills, agencies contacted, and in-house lobbyists engaged.
KOCH GOVERNMENT AFFAIRS leads all filers on this issue with $17.8M in tracked lobbying expenditures, and the top 10 reporting organizations - including KOCH GOVERNMENT AFFAIRS, NATIONAL ASSOCIATION OF HOME BUILDERS, AMERICAN FEDERATION OF STATE COUNTY AND MUNICIPAL EMPLOYEES - typically account for a disproportionate share of total outlays, a concentration pattern that repeats across most LDA issue codes. Each of these organizations files quarterly LD-2 disclosures naming the lobbyists deployed and the chambers of Congress or executive agencies contacted.
The 68 filers tracked here represent a structured picture of who is paying to be heard on Constitution - useful context when evaluating hearings, committee markups, and rulemaking on related topics. Because LDA filings are a public-record trailing indicator, spending in the 2023-2024 window reflects priorities that will continue to ripple through the 118th and 119th Congresses before any policy outcomes register in the data.
