From Public Citizen:
Shine Sunlight on Election Spending
Tell Your Senators to Pass the DISCLOSE Act
If a group is trying to influence your vote, then you should know who is paying them to do so.
That is the commonsense principle behind the DISCLOSE Act (S. 2219, H.R. 4010) – a bill to require that the identities of those who fund election-season political ads be disclosed to the public, regardless of whether that funding comes from corporations, labor unions or millionaires and billionaires.
Use the form below to tell your senators to support the DISCLOSE Act.
Please type your zip code into the box below. Then take a moment to add your own words to the email message that appears. This greatly increases the likelihood that your message will make a difference. You can also ask your senators to support the DISCLOSE Act by phone by calling the U.S. Capitol Switchboard at (202) 224-3121. Let us know how it goes with an email to action (at) citizen (dot) org!
