All the articles I've seen said she falsely claimed to be 1/32 Cherokee. This from Wikipedia:
"Warren herself represented that both her mother
[34] and her Aunt Bea
[35] were white on death certificates filed with the State of Oklahoma.
Initial claims by a genealogist in Boston that Warren was 1/32 Cherokee were withdrawn
[36] as lacking evidence.
[37] The Boston Globe had promoted the news that Warren was 1/32 Cherokee, but when the lack of evidence was discovered, The Boston Globe printed the correction in a section of the paper
[38] unlikely to be noticed by the public.
All known evidence shows that Warren’s family always self-identified as white, and
her great grandfather even was identified in local newspapers as white when it was reported that he shot an Indian.[39]"
Her great grandfather reportedly shot an Indian so perhaps to a Dem that qualifies her as 1/64. And I mean no offense to Indians by mentioning her claim to be of Native American descent. Never fear, she wasn't.
