Crs Report for Congress

Super PACs emerged after the U.S. Supreme Court permitted unlimited corporate and union spending on elections in January 2010 (Citizens United v. Federal Election Commission). Although not directly addressed in that case, related, subsequent litigation (SpeechNow v. Federal Election Commission) and Federal Election Commission (FEC) activity gave rise to a new form of political committee. These entities, known as super PACs or independent-expenditure-only committees (IEOCs) have been permitted to accept unlimited contributions and make unlimited expenditures aimed at electing or defeating federal candidates. Super PACs may not contribute funds directly to federal candidates or parties.
