Sen. Elizabeth Warren revealed the results of a DNA test Monday, bolstering both her claims to a Native American heritage — and the near-certainty that she’ll run for president in 2020.
Warren's heritage is a favorite talking point for President Donald Trump, who routinely mocks her background, calling her “Pocahontas” and claiming that she fudged her ancestry to get ahead. Warren, who is originally from Oklahoma, has long insisted that she was told as a child that she inherited Native American roots from her great-great-great-grandmother.
Apparently, that insistence resulted in a DNA analysis from Carlos D. Bustamante, a Stanford University professor, who concluded that, while she’s mostly European, her “results strongly support the existence of an unadmixed Native American ancestor” about six to 10 generations removed from the Massachusetts senator.
That means she could be 1/32nd American Indian, or 1/1,024 Native American. This difference will likely be highlighted by Republicans, who have called into question whether she unfairly benefitted from claiming Native American heritage during her time as a law professor at the University of Texas at Austin School of Law, the University of Pennsylvania, and Harvard Law School.
Either way, it’s a pretty remarkable show of transparency compared to a president who has refused to release his tax returns or otherwise disclose his true wealth. Warren, on the other hand, sent a sample of her DNA to a private, Georgia-based lab in August, according to the Boston Globe. The Globe has also reviewed whether her heritage had an impact on her legal career, and found none.
Trump once offered Warren $1 million if she took a DNA test “and it shows you’re an Indian,” according to the Washington Post. On Monday, he denied saying it, even though it was televised.
In the meantime, Warren has since added all of this information to part of her official website, detailing her ancestry in a nearly six-minute, folksy video featuring family members in Oklahoma.
“I used my mama’s grit to get through commuter college and law school,” Warren says in the video’s voiceover. “I used my daddy’s relentless optimism when I was balancing babies and books. But my background played no role in my hiring.”
