did you read this in your link? "A national politician has taken a DNA test to prove her heritage. To which President Donald Trump, who has repeatedly mocked Warren as “Pocahontas,” responded on Monday, “Who cares?” It was Trump himself who purported to care. At a July rally, he said he’d toss Warren a DNA kit, even suggesting he would donate a million dollars to charity if she took it. Trump today: “I didn’t say that". you're hero wouldn't welsh and then lie about it, would he?
Not only it is not definitive, it is the pinnacle of voodoo junk science.... The DNA test showed that she has less Native blood than the average American... "U.S. Senator Elizabeth Warren (D-Mass.) released the results of a DNA test Monday to prove that she does indeed have Native American ancestry, which has not worked out as planned. “To make up for the dearth of Native American DNA, Bustamante used samples from Mexico, Peru and Colombia to stand in for Native American,” the Boston Globe report said. In other words, Warren’s DNA could be Mexican, Peruvian, Colombian or Native American, but the “scientist” behind the test simply assumed that if Warren possessed Mexican, Peruvian or Colombian DNA that she was indeed Native American."
