Clinton foundation admits mistakes on tax filings

The Clinton Foundation defended its commitment to transparency on Sunday, but also admitted that the organization had made mistakes in its tax filings.

Maura Pally, acting CEO of the foundation, posted a statement Sunday acknowledging that while the organization had not underreported its revenue, it had failed to separate government grants from other donations on its tax filings. Pally wrote that after a voluntary external review, the foundation intends to refile several years' worth of forms.

"Yes, we made mistakes, as many organizations of our size do, but we are acting quickly to remedy them, and have taken steps to ensure they don't happen in the future," Pally wrote in the statement. "We are committed to operating the Foundation responsibly and effectively to continue the life-changing work that this philanthropy is doing every day." She added that the organization's "donor disclosure and foreign government contributor policy is stronger than ever."
