Elizabeth Warren is again under scrutiny for claiming Native American ancestry.

It’s a cloud that will no doubt put a damper on her almost certain run for President.

The latest controversy comes after the Washington Post uncovered a registration card from 1986 for the Texas Bar in which Warren listed her race as “American Indian” in her own handwriting.

Her comments more fully explain the regret she expressed last week to the chief of the Cherokee Nation, the first time she’s said she was sorry for claiming American Indian heritage.

The private apology was earlier reported as focusing more narrowly on a DNA test she took to demonstrate her purported heritage, a move that prompted a ferocious backlash even from many allies. Warren will be vying to lead a party that has become far more mindful of nonwhite voters and their objections to misuse of their culture.

“I can’t go back,” Warren said in an interview with The Washington Post. “But I am sorry for furthering confusion on tribal sovereignty and tribal citizenship and harm that resulted.”

On Twitter, one observer suggested that Warren and her political aspirations will not survive this renewed controversy:

Warren’s claim of Native American ancestry has often become both a punchline and a line of attack for Donald Trump — who has frequently sought to disparage her by calling her “Pocahontas.”

Donald Jr. called the timing of the discovery “suspicious”:

Suspicious timing for this to come out. It’s almost like Elizabeth Warren is trying to hide what I’ve said all along about taking advantage of her fake Native American heritage at the expense of real Native Americans and minorities. pic.twitter.com/ZeKbYa23Jq

This is from Elizabeth Warren’s registration for the Texas Bar, filled out in her own hand and calling herself “American Indian.” She has insisted she never used that identity to “get ahead.” You decide. pic.twitter.com/3ykomyAMKp
