About Sludge

Sludge produces investigative journalism on lobbying and money in politics. We look beyond public records and disclosures to reveal the hidden networks and conflicts of interest that drive systemic corruption.

Sludge reports on the ways industries launder their agendas through independent groups, the power maps of corporate networks that extend deep into government, how concentrated economic powers dictate public policy, and more. We scour traditional lobbying disclosures and campaign contributions, but our primary focus is all the ways that money influences politics that don’t fit established patterns and often don’t have to be disclosed.

As special interests try to hide their lobbying, Sludge is committed to exposing them.


Sludge never takes money from advertisers, interest groups, or corporations, so we are solely focused on providing information that our members value. Because we don’t rely on advertisements for revenue we never produce “clickbait” to pay our bills and we never shy away from topics that challenge powerful interests.

Sludge members contribute $5/month to receive the special Sludge Report email newsletter or $9/month for behind-the-scenes access to our team of reporters. Sludge’s reporters host members-only Q&A sessions to dig in deeper on stories, answer questions about process, and get to know our members and what areas of research they care about.
