NEW YORK (Reuters) – Hillary Clinton’s family’s charities are refiling at least five annual tax returns after a Reuters review found errors in how they reported donations from governments, and said they may audit other Clinton Foundation returns in case of other errors.

The foundation and its list of donors have been under intense scrutiny in recent weeks. Republican critics say the foundation makes Clinton, who is seeking the Democratic presidential nomination in 2016, vulnerable to undue influence. Her campaign team calls these claims “absurd conspiracy theories.”

The charities’ errors generally take the form of under-reporting or over-reporting, by millions of dollars, donations from foreign governments, or in other instances omitting to break out government donations entirely when reporting revenue, the charities confirmed to Reuters.

The errors, which have not been previously reported, appear on the form 990s that all non-profit organizations must file annually with the Internal Revenue Service to maintain their tax-exempt status. A charity must show copies of the forms to anyone who wants to see them to understand how the charity raises and spends money.

The unsettled numbers on the tax returns are not evidence of wrongdoing but tend to undermine the 990s role as a form of public accountability, experts in charity law and transparency advocates told Reuters.

“If those numbers keep changing – well, actually, we spent this on this, not that on that – it really defeats the purpose,” said Bill Allison, a senior fellow at the Sunlight Foundation, a government transparency advocacy group.

For three years in a row beginning in 2010, the Clinton Foundation reported to the IRS that it received zero in funds from foreign and U.S. governments, a dramatic fall-off from the tens of millions of dollars in foreign government contributions reported in preceding years.

Those entries were errors, according to the foundation: several foreign governments continued to give tens of millions of dollars toward the foundation’s work on climate change and economic development through this three-year period. Those governments were identified on the foundation’s annually updated donor list, along with broad indications of how much each had cumulatively given since they began donating.
