President Donald Trump apparently owes a million dollars to charity after Sen. Elizabeth Warren (D-MA) took a DNA test proving her Native American ancestry.

The president has routinely mocked Warren with the racist taunt "Pocahontas," and he pledged a donation to the charity of her choice if she could prove her heritage.

“I will give you a million dollars to your favorite charity, paid for by Trump, if you take the test and it shows you’re an Indian,” Trump said July 5 at a rally in Great Falls, Montana. "Let's see what she does. I have a feeling she will say no, but we'll hold that for the debates."

Warren released an ad Monday morning revealing the results of a DNA test that shows "strong evidence" of Native American ancestry, ahead of a possible 2020 presidential run.

Warren called the president's bluff and challenged him to make a donation to the National Indigenous Women’s Resource Center -- then warned him to release his taxes before Democrats forced him to do so.
