The Clinton Foundation has acknowledged that the government funding totals omitted from their tax returns cannot be found on their website either, despite the foundation's acting chief executive officer earlier suggesting they were available there.

The foreign government funding received by the globe-spanning charities of Hillary Rodham Clinton's family has received particular scrutiny in recent weeks as Clinton seeks to become the Democratic nominee in the 2016 presidential election.

The foundation's acknowledgement means precise totals for government grants to the charity for the last three years of Clinton's four-year tenure as secretary of state have still not been publicly disclosed. All U.S. charities have to separately disclose each year how much they get in government funding, both domestic and foreign.
