OpenSecrets is a nonprofit organization based in Washington, D.C. that tracks and publishes data on campaign finance and lobbying, including a revolving door database which documents the individuals who have worked in both the public sector and lobbying firms and may have conflicts of interest. It was created from the 2021 merger of the Center for Responsive Politics (CRP) and the National Institute on Money in Politics (NIMP), both of which were organizations that tracked data on campaign finance in the United States and advocated for stricter regulation and disclosure of political donations.
