Biden's contributors include outside groups that don't disclose donors, but there is no evidence to suggest backing from Iranian anti-American regimes
The campaign of now President-elect Joe Biden began on April 25, 2019, when he released a video announcing his candidacy in the 2020 Democratic party presidential primaries. Since then, Biden has raised a total of $702 million, including donations to his official campaign committee and outside groups like single-candidate super PACs and hybrid PACs that do not require donor disclosure. The Biden campaign released a list of 817 people who have helped raise at least $100,000 each to support Biden's presidential run. But none of this data indicates he is supported by anti-American regimes in Iran.
