Sen. Elizabeth Warren's DNA analysis points to a Native American heritage

Responding to years of derision by President Donald Trump and other critics, Sen. Elizabeth Warren had a DNA analysis done that provides strong evidence she does, in fact, have Native American heritage.

The analysis on the the Massachusetts Democrat was done by Stanford University professor Carlos D. Bustamante, The Boston Globe reported Monday. He concluded Warren's ancestry is mostly European but says "the results strongly support the existence of an unadmixed Native American ancestor."

Bustamante, a prominent expert in the field of DNA analysis, determined Warren's pure Native American ancestor appears "in the range of six to 10 generations ago."

That meshes with Warren's narrative that her great-great-great-grandmother, O.C. Sarah Smith, was at least partially Native American. That would make Warren 1/32nd Native American.

But if her ancestor is 10 generations back, that could mean she's just 1/512th Native American, something that could further excite her critics instead of placating them.

Those critics have charged that Warren advanced her career with a narrative she is a descendant of Cherokee and Delaware tribes. Trump has repeatedly mocked her as "Pocahontas," going so far as to offer $1 million to a charity of her choice if she took a DNA test that proved her claims.

Warren is seeking re-election to a second term in Massachusetts and is a potential 2020 presidential contender. Her Senate campaign produced a video posted on The Globe's website in which Warren says: "The president likes to call my mom a liar. What do the facts say?"

Bustamante replies: "The facts suggest that you absolutely have Native American ancestry in your pedigree."
