super-PACs

Independent expenditure-only political action committees, commonly known as super PACs, are a type of political action committees (PACs) in the United States. Unlike traditional PACs, super PACs are legally allowed to fundraise unlimited amounts of money from individuals or organizations for the purpose of campaign advertising; however, they are not permitted to either coordinate with or contribute directly to candidate campaigns or political parties. However, in practice, restrictions on such coordination are considered flimsy and poorly enforced.
