President Biden‘s 2024 candidacy is likely to benefit from massive undisclosed donations from the main outside super PAC supporting him, according to records.

The Future Forward PAC, promoted by Biden’s team as a leading external group to raise funds for his campaign, reported just $67,000 in contributions during the first half of the year.

However, the money appears to be in its affiliated dark money nonprofit, Future Forward USA Action, which has a history of transferring tens of millions to the PAC for electoral activities.

Future Forward’s use of secretive donations raises concerns about transparency and leaves the American people in the dark about the sources of funds influencing Biden’s re-election. The nonprofit’s connections to the Arabella Advisors consulting firm, which manages a billion-dollar dark money network, add an extra layer of concealment regarding its original donors.

During the last presidential cycle, the Impetus Fund, another dark money group, sent $55.8 million in undisclosed cash to Future Forward USA Action.

The nonprofit has transferred a total of $77 million to the Future Forward PAC since the 2020 election, accounting for more than 40% of the PAC’s total fundraising during that time.

Senior White House adviser Anita Dunn praised Future Forward’s effectiveness and rigorous testing, which impressed the Biden campaign during the 2020 election. However, with a significant amount of cash flowing through dark money channels, concerns about the source and influence of these donations persist.

Future Forward did not respond to requests for comment from Fox News Digital.
