Center for Responsive Politics

Founded in 1983, the Center for Responsive Politics (CRP) is the nation's premier research group tracking money in U.S. politics and its effect on elections and public policy. Independent and nonpartisan, we make our data, analysis and public interest journalism freely available on our website, OpenSecrets.org. Our vision is for Americans to be empowered by access to clear and unbiased information about money's role in politics and policy and to use that knowledge to strengthen our democracy. Our mission is to produce and disseminate peerless data and analysis on money in politics to inform and engage Americans, champion transparency, and expose disproportionate or undue influence on public policy.
