About the data

This data is compiled using OpenSecrets bulk data downloads. LittleSis analysts match federal campaign contributions given by individuals in our database using the donation matching tool.

Individual profile pages show giving information for the individual profiled; org pages show an aggregate analysis of giving information for individuals with positions or memberships at those orgs. Note that this information may differ substantially from data found at InfluenceExplorer or OpenSecrets, because it only includes donations for individuals in our database who have been donor-matched by an analyst.
