Sunlight’s Checking Influence: Find the Politics in Your Pocketbook


The Sunlight Foundation is proud to announce our Checking Influence tool that gives individuals the power to see the political expenditures of the businesses you frequent.

A Note About Security

We understand that everyone is cautious about banking information online (and rightfully so!), which is why the Sunlight Foundation has taken a number of steps to ensure that Checking Influence is safe to use.
