Citizens United:
where does Congress stand?
Sixteen years after the ruling, a constitutional amendment to overturn it needs 290 House and
67 Senate votes. In the House, the
Sixteen Years of Unlimited Money
Super PACs did not exist in 2009. In the sixteen years since Citizens United v. FEC removed limits on independent political spending by corporations and unions, "outside groups" — spenders other than the candidates' own campaigns — have rebuilt how American elections are paid for. They spent a record $4.5 billion on the 2024 federal elections, and more than half of it came from groups that never fully disclose whose money it is. The ruling freed nonprofit corporations too, which is where "dark money" enters. Shell companies and dark-money groups pumped over $1 billion into super PACs in 2024 alone — in 2016 that figure was under $72 million.
Congress holds two levers against this: a constitutional amendment to end the unlimited spending, and a disclosure law to end the secrecy. This page tracks both, daily. The amendment count so far: six vehicles pending in the 119th Congress, none advanced to a floor vote, with

Citizens United vs. Dark Money — Two Fights, Two Fixes
The two phrases travel together, and they are related — Citizens United supplies the "unlimited," the tax code supplies the "dark." The 2010 ruling gave corporations and unions the right to spend without limits on elections, so long as the spending stays independent of campaigns — and "corporations" includes nonprofits, the vehicle of choice for anonymous spending. (Citizens United, the plaintiff, was itself a nonprofit corporation.) The ruling did not create the secrecy: the Court upheld disclosure requirements 8–1, on the assumption that voters would always know who was paying.
That assumption failed. Spending routed through 501(c)(4) "social welfare" nonprofits stays anonymous because the tax code does not require those groups to name their donors, and Congress has never closed the gap. The two problems also take different-sized fixes: ending unlimited spending requires the constitutional amendment tracked above — 290 House and 67 Senate votes. Ending the secrecy requires only an ordinary statute: the DISCLOSE Act, which would force any group spending in elections — super PACs and dark-money nonprofits alike — to reveal donors who give more than $10,000.
"Outside spending" — election spending by anyone other than the candidates' own campaigns: super PACs, parties' independent expenditures, and politically active nonprofits. This is the spending Citizens United deregulated. 2024 total: a record $4.5 billion.
"Never fully disclosed" — more than half of that $4.5 billion was spent by groups that do not reveal where their money originally came from. A super PAC names its direct donors, but when the donor is a shell company or a nonprofit, the true source stays hidden.
The $1 billion+ "dark-money pipeline" — a different, narrower measurement: dollars that shell companies and dark-money nonprofits contributed into super PACs in 2024, up from $72 million in 2016. It is the traceable slice, not the total.
Total dark money — genuinely uncountable: much nonprofit political spending is never reported to the FEC at all. Every figure above is from OpenSecrets' post-2024 analysis.
The DISCLOSE Act — tracked
How we count: "backers" = the sponsor plus cosponsors listed on Congress.gov — members who have put their names on the bill in writing. The House bar measures against 218, a simple majority; the Senate bar against 60, the votes needed to beat a filibuster (a statute needs only a majority to pass, but 60 to get a vote at all). Cosponsorship is a floor, not a ceiling: members can vote yes without cosponsoring — in 2022, every Democrat present did, cosponsor or not.
When the Senate last voted on the DISCLOSE Act, in September 2022,
every Democrat present voted to advance it and every Republican present voted no — 49–49, eleven votes
short of breaking the filibuster. The 2026 version has
What Members Are Saying
The parties use the same words for opposite purposes: Democrats and Independents invoke "dark money" to argue for overturning Citizens United or mandating disclosure; Republicans in our archive use it to describe left-leaning donors and groups, and none supports an overturn amendment.

Sponsor and cosponsor data: Congress.gov API, retrieved August 31, 2026 — counts change as members sign on; this page reflects that date. Member quotes are drawn from WhosMyRep.org's archive of official congressional social media accounts, which covers approximately the past year; quotes are reproduced as members posted them and characterizations ("poisoned our politics," "dark money machine") are the members' own. Descriptions of what Citizens United v. FEC (2010) held are summarized at a high level here; a full explainer with the underlying case line (Buckley v. Valeo, Austin, McConnell) is planned. This page is generated with AI assistance from structured congressional data; the vote counts and cosponsor tallies are computed directly from Congress.gov records, not by a language model.
