President Trump will follow through on a pledge to donate $1 million to the charity of Sen. Elizabeth Warren’s choosing, only if he can administer a DNA test to her personally, he said Monday.

“I’ll only do it if I can test her personally,” Trump told reporters during a stop in Georgia where he received a briefing on Hurricane Michael. “That will not be something I enjoy doing either.”

The president said during a rally in July in Montana that he would make a $1 million donation to a charity if Warren underwent a DNA test that showed she has Native American ancestry.

The Democratic Massachusetts lawmaker did take a DNA test, the results of which were shared with the Boston Globe on Sunday. Analysis of the results showed there is “strong evidence” Warren has a Native American ancestor “in the range of 6-10 generations ago.”

Earlier Monday, Trump denied saying he would make the donation if Warren took a DNA test that proved her Native American ancestry. But when pressed about his pledge later in the day, the president offered more specific details as to the terms of his deal.

“You mean if she gets the nomination, in a debate is where I was going to have her tested,” Trump said.

The president also said he does not owe Warren, who he calls "Pocahontas," an apology.

"She owes the country an apology," he said.
