A bill to amend the Federal Election Campaign Act of 1971 to provide for additional disclosure requirements for corporations, labor organizations, Super PACs and other entities, and for other purposes.

S. 3991 would amend the Federal Election Campaign Act of 1971 to impose expanded disclosure requirements on corporations, labor organizations, Super PACs, and other entities involved in political spending. The bill, introduced by Senator Sheldon Whitehouse (D-RI) on March 4, 2026, is currently under committee consideration.

If enacted, this legislation would require these organizations to provide more detailed information about their political contributions and spending activities. The practical effect would be to increase transparency around money flowing into elections, allowing citizens and voters to better understand who is funding political campaigns and advertisements. Currently, some political spending occurs through channels with limited disclosure requirements, and this bill would aim to close those gaps.

The bill has not yet been voted on by the full Senate. As standard legislation, it would require presidential signature to become law if it passes both chambers of Congress.
