As Democratic lawmakers and allies continue to blast No Labels for its third-party ballot initiative, groups are now turning to campaign finance complaints to uncover the organization’s donors.

No Labels has been stockpiling cash from donors, which the group does not disclose, for months, working tirelessly to gain access to ballots in all 50 states for the 2024 election. Democratic groups have accused the group of working to prevent President Joe Biden‘s reelection and aiding a GOP victory, an accusation No Labels has adamantly denied.
