The Sunlight Foundation’s OpenCongress project enables anyone to follow and explore the activities of Congress, and it has become a leading comprehensive, nonpartisan source for legislative information. With support from the Rita Allen Foundation, the Sunlight Foundation is redesigning the tool with user-centered principles as a new platform for all of Sunlight’s federal data, beyond the site’s current focus on legislators, bills and votes. Sunlight is integrating it with other tools and real-time data about congressional actions and political influence, and is spreading it to wider audiences.
