The Clinton Administration admitted in a statement Sunday that it has made mistakes in its tax forms.

According to Washington Post, the acting chief of the Bill, Hillary and Chelsea Foundation acknowledged that the philanthropy has made missteps but that it does not amount to the organization's charitable work or its commitment to transparency.

The statement defends against critics who say Hillary Clinton's relationship with donors have helped to give her a better reputation as she heads into the 2016 presidential campaign.

"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," the foundation's acting chief executive officer, Maura Pally, said 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."

Pally's response comes at a time when reports say that Hillary Clinton headed an operation that signed off on a uranium production deal with Russia, The New York Times reports.

According to the report, as Russians gained control over Uranium One, the Clinton Administration accepted a flow of cash from the foreign company. The Clinton's allegedly never disclosed that they received a total of $2.35 million in donations from Uranium One's chairman.

"Should we be concerned? Absolutely," said Michael McFaul, who was the American ambassador under Hillary Clinton at the time. "Do we want Putin to have a monopoly on this? Of course we don't. We don't want to be dependent on Putin for anything in this climate."

McFaul says he was unaware about the transactions from Uranium One.

Meanwhile, the Clinton Foundation vows to institute new commitments in disclosing it donors. Although it is not required by law, the foundation began disclosing its donors each year when Mrs. Clinton became secretary of state in 2009.

The foundation announced that it would accept donations only from a handful of countries when the former secretary of state entered the presidential race.
