Sen. Elizabeth Warren (D-Mass.) shared DNA test results on Monday that provided "strong evidence" of some Native American ancestry. The result, and a video accompanying the announcement, came in response to a challenge from President Trump, who in July said he'd give $1 million to her "favorite charity" if she proved her Cherokee ancestry. Asked about his previous comments, Trump denied promising anything, then later said he'd only donate money if he could "test her personally" if she ran for president in 2020. The Cherokee Nation said in a statement that Warren "is undermining tribal interests with her continued claims of tribal heritage." The test indicates she's no more that 1/32 Native American, with a native ancestor in her family between six and 10 generations ago.
