The Problem

The Lobbying Disclosure Act requires lobbyists to file quarterly reports with the Senate. These filings are public record — but they're buried in a government database with a terrible interface. Most people have no idea who's lobbying their representatives, how much they're spending, or what they want.

What We Do

We download every lobbying filing from the Senate LDA database, process it, and present it in a way that's actually useful. Search by client, firm, lobbyist, issue, or keyword. Track spending trends over time. Read our investigations into the most interesting patterns.
