Federal law formally allows for two types of PACs: connected and non-connected. Judicial decisions added a third classification, independent expenditure-only committees, which are colloquially known as "
super PACs".
Connected PACs Most of the 4,600 active, registered PACs, named "connected PACs", sometimes also called "corporate PACs", are established by businesses, non-profits, labor unions, trade groups, or health organizations. These PACs receive and raise money from a "restricted class", generally consisting of managers and shareholders in the case of a corporation or members in the case of a non-profit organization, labor union or other interest group. As of January 2009, there were 1,598 registered corporate PACs, 272 related to labor unions and 995 to trade organizations.
Non-connected PACs Groups with an ideological mission, single-issue groups, and members of Congress and other political leaders may form "non-connected PACs". These organizations may accept funds from any individual, connected PAC, or organization. As of January 2009, there were 1,594 non-connected PACs, the fastest-growing category. Under the FEC (Federal Election Commission) rules, leadership PACs are non-connected PACs, and can accept donations from individuals and other PACs. Since current officeholders have an easier time attracting contributions, Leadership PACs are a way dominant parties can capture seats from other parties. A leadership PAC sponsored by an elected official cannot use funds to support that official's own campaign. However, it may fund travel, administrative expenses, consultants, polling, and other non-campaign expenses. In the 2018 election cycle, leadership PACs donated more than $67 million to federal candidates. The number remained steady during the 2024 election cycle, with leadership PACs donating nearly $69 million to federal candidates. According to the government watchdog group
OpenSecrets, 764 total PACs donated about $41.5 million to Republicans and $26.5 million to Democrats.
Controversial use of leadership PACs • Former Rep.
John Doolittle's (R-CA) leadership PAC paid 15% to a firm that employed only his wife. Payouts to his wife's firm were $68,630 in 2003 and 2004, and $224,000 in 2005 and 2006. The Doolittle home was raided in 2007. After years of investigation, the Justice Department dropped the case with no charges in June 2010. • Former Rep.
Richard Pombo (R-CA) used his leadership PAC to pay hotel bills ($22,896) and buy baseball tickets ($320) for donors. • Speaker of the House
Nancy Pelosi's (D-CA) leadership PAC, Team Majority, was fined $21,000 by federal election officials "for improperly accepting donations over federal limits." • President Trump's leadership PAC
Save America paid $650,000 for portraits of him and the first lady that will one day hang in the
Smithsonian's
National Portrait Gallery, $200,000 to Trump Hotel properties, and $132,000 to First Lady
Melania Trump's
fashion stylist.
Super PACs Super PACs, officially known as "independent expenditure-only political action committees," are unlike traditional PACs in that they may raise unlimited amounts from individuals, corporations, unions, and other groups to spend on, for example, ads overtly advocating for or against political candidates. However, they are not allowed to either coordinate with or contribute directly to candidate campaigns or political parties. Super PACs are subject to the same organizational, reporting, and public disclosure requirements of traditional PACs.
Hybrid PACs A hybrid PAC (sometimes called a Carey Committee) is similar to a super PAC, but can give limited amounts of money directly to campaigns and committees, while still making independent expenditures in unlimited amounts. ==Top PACs by election cycle==
