It's the latest in a string of admissions from the foundation that it didn't always abide by a 2008 ethics agreement to disclose its funding sources publicly. That agreement, penned as Hillary Clinton became secretary of state, is certain to continue the headache that the foundation's work and donors have become for Clinton as she makes another run at the White House.
According to foundation officials, the income -- at least $12 million and as much as more than twice that -- was not disclosed publicly because it was considered and tallied for tax purposes as revenue, rather than donations.
In April, the head of a Canadian charity that donates to the foundation acknowledged that it didn't disclose any of the 1,100 largely foreign donors that ultimately contributed $2.35 million to the broader organization through the Canadian group.
