Haaland praised Warren hours after the potential 2020 presidential candidate released the results of a DNA test showing she has a distant Native ancestor. She unveiled the results in a video that featured remarks from her family members in Oklahoma, as well as past employers.

She provided the results to a renowned genealogist, who determined that the results "strongly support" Warren had a Native American ancestor, likely six to 10 generations ago.

Trump dismissed the test results on Monday morning, telling reporters, "Who cares?"

He went on to claim he never said he would donate $1 million to a charity of Warren's choosing if she took a DNA test, even though he made that pledge during a July campaign rally in Montana.

"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 at the time. "I have a feeling she will say 'no.'"

In a series of tweets on Monday, Warren called on Trump to pay the $1 million to a charity that benefits Native American women who are victims of sexual violence and violent crimes.
