A political action committee: a group registered with the Federal Election Commission that raises money and spends it on elections, including by giving to candidates. Corporations, labor unions, trade associations and membership groups can sponsor one, which may raise money only from people tied to the sponsor (its employees, members or shareholders, for example). Independent (nonconnected) PACs can raise from the public, and many politicians have a leadership PAC to give to other candidates. In 2025–26 a PAC that gives to several candidates can give each one up to $5,000 per election.

A committee that can raise unlimited sums from individuals, corporations, unions and other PACs, but only to spend independently: ads and other activity not coordinated with a campaign. It doesn't give to campaigns, so super PAC money isn't in the PAC totals here.

What is a bundled (earmarked) donation?

A donation from an individual that a group collects and passes on to the candidate it's earmarked for. Under federal rules it counts as that individual's own contribution (up to $3,500 per election in 2025–26), and the campaign reports it as earmarked through the group. It's separate from the PAC's own direct contributions.

What's a PAC?

A political action committee (PAC) is a group registered with the Federal Election Commission that raises money and spends it on federal elections, including by giving to candidates' campaigns. The FEC sorts them into a few kinds:

Corporate, labor union, trade association and membership PACs are sponsored by an organization and may raise money only from people tied to it, such as its employees, members or shareholders. The FEC calls them "separate segregated funds."
Nonconnected PACs have no sponsoring organization and can raise money from the public.
Leadership PACs are run by a politician, separate from their own campaign, often to give to other candidates.
Super PACs can raise unlimited sums from individuals, corporations, unions and other PACs, but only to spend independently: ads and other activity not coordinated with a campaign. They don't give to campaigns, so they aren't in the PAC totals here. Outside spending is shown on each candidate's page and on the presidential page.

Limits: in 2025–26 a PAC that gives to several candidates can give each one up to $5,000 per election (the primary and the general count separately). An individual can give a candidate up to $3,500 per election. FEC contribution limits.

Bundled (earmarked) gifts: a group can also collect donations from individuals and forward them to the candidates the donors earmarked them for. Each one counts as the donor's own contribution, under the donor's limit, and the campaign reports it as earmarked through the group. That's why we count it separately from a PAC's direct giving. Federal rule (11 CFR 110.6).

From the FEC's guide to PACs. Giving to a campaign is legal and public; who gave doesn't tell you how a member votes. Compare their voting record and placement on their candidate page.

How we count

Who's counted: the current members of the House (including its nonvoting delegates) and Senate, from the House Clerk's and the Senate's own member lists.
Direct PAC money: contributions (including in-kind) from a PAC's own account to a member's campaign committees, January 2023 through the latest 2026 reports (the FEC's 2024 and 2026 cycles), from the FEC's bulk data. Party committees and other candidates' campaigns are counted separately and aren't ranked.
Bundled gifts: donations from individuals that a group collected and forwarded to a campaign, which the campaign reports to the FEC as earmarked through that group. The money comes from the individual donors; the group collected and passed it on. Payment platforms that process gifts for any campaign (ActBlue, WinRed, Democracy Engine) aren't counted as bundlers.
Which PACs are listed: the 50 that gave current members the most directly, and the 25 that forwarded the most in bundled gifts, by dollars, whatever their side or industry. The two lists are kept apart, and each group's page shows both amounts. Categories (corporate, labor union, trade association, membership organization, nonconnected or leadership PAC) are the FEC's own.
What each PAC supports: a short description from the group's own website or FEC filing, written the same way for every group. A group that doesn't publish one is marked as such; we don't fill it in.
Not counted: super PAC and other outside spending, which goes to ads and canvassing rather than to the campaign (shown separately for the presidential race).
Presidential: the FEC's presidential campaign summaries for 2024. Gift sizes include money that came through joint fundraising committees. Outside spending is independent expenditures reported to the FEC.
Updates: refreshed as new reports are filed. Members elected on November 3, 2026 take office in January 2027; the lists switch then.
