Lobbying
Who pays Washington lobbyists, how much, and on which issues.
About this data
- What it is
- Companies and trade groups that pay for lobbying must report it to Congress every quarter: who they hired, how much they spent, and which issues were lobbied.
- Who files it
- The lobbying firm, or the company itself when it uses its own staff, under the Lobbying Disclosure Act.
- How current
- Quarterly reports are due 20 days after each quarter ends, so they arrive in waves. We collect them daily.
- Worth knowing
- Amounts are rounded by the filer and cover the whole quarter. We match clients to listed companies automatically, so a few may be missed or misattributed.
All of this comes from public filings.
