Lobbying is legal. It's also one of the most important and least-understood forces in American politics. Here's how to read it.

What lobbying is

Lobbying is any attempt to influence legislation or regulation by communicating directly with government officials. It's protected by the First Amendment. Lobbyists are professionals paid to represent clients — corporations, trade associations, foreign governments, nonprofits — before Congress and federal agencies.

The disclosure system

The Lobbying Disclosure Act (LDA) requires lobbyists to register with the Senate and file quarterly reports showing:

Which clients they represent
How much those clients paid them
Which issues they lobbied on (by broad category)
Which specific bills they mentioned
Which agencies or chambers of Congress they contacted

Capitol Trace pulls all of these filings.

The revolving door

The most powerful lobbyists are often former members of Congress or senior government officials. They bring relationships, institutional knowledge, and access that career lobbyists can't match.
