Sludge is an independent newsroom focused on money in politics, co-founded by David Moore and Donny Shaw of the 501(c)3 non-profit Participatory Politics Foundation. 100% of your tax-exempt donations to PPF will go to support Sludge's investigative journalism.

Sludge's mission is to increase public accountability by following the money: campaign contributions, lobbying, dark money, and all the ways that powerful special interests evade public disclosure laws. About us and our impacts.
