The new DISCLOSE Act of 2012, S. 3369, would not require disclosure until these groups spend $10,000 or more in aggregate, and would also remove other pieces from the 2010 bill in a bid to streamline it and make it easier for companies and other groups to comply.
But it would require reporting for each $10,000 in spending, and would subject companies, labor unions and super PACs to this rule. However, it would not require parties, candidate committees or charitable organizations to file these reports.
Democrats are hoping this moderated version might succeed where the last bill failed. In 2010, the prior version from Democrats passed in the House, but failed in a procedural vote in the Senate in September 2010.
Democrats have been looking to limit the impact of the Citizens United decision since 2010 in an effort to limit the influence of corporate money in campaigns.
"The Supreme Court's decision in Citizens United v. FEC opened the floodgates to unlimited corporate and special-interest money in elections, bringing about an era where corporations and other wealthy interests can exert vastly disproportionate influence in our political system, including through anonymous donations," according to a summary from Whitehouse's office.
