Neither Warren nor her office either denied the authenticity of the document or it was the senator's signature on it. "I can't go back," Warren told the post in an interview Tuesday. "But I'm sorry to promote confusion about tribal sovereignty and tribal citizenship and damage that resulted."
Here's why it all matters so much: Before Posten's report on this bar registration card, Warren had maintained some level of plausible denitability of claiming himself as an Indian. As the record wrote:
"Texas bar registration card is essential among other reasons because it eliminates any doubt that Warren directly claimed the identity. In other cases, Warren has declined to say whether she or an assistant filled out forms. "
When subsequent stories arose about Warren being listed as an Indian in a similar faculty catalog by the University of Pennsylvania, the Warren team gave the same answer. She was not aware of the listing – and certainly never got any benefit from it.
But that didn't do that. First of all, it rehashed much of what Warren had previously said about her allegations of having native American ancestors – that she had been told by her family that her ancestors were American Indians. Second, it attempted to hang the verification of her claims for a DNA test that suggested she might have had native American ancestors six to ten generations ago.
It wasn't just something that was unclear, but it also worried Cherokee Nation who claimed to define ethnicity via DNA and bloodlines was a dicey proposition.
What we now know is that Warren was actively identified as an Indian as far back as 1986. This was not a mix or misunderstanding or anyone who worked for Warren made a mistake. This was Warren's work.
It still does not mean that she has got anything from her decision to call herself an Indian on some documents. The bar registration card is a simple formality, not the kind of thing that somehow will benefit Warren in any significant way.
But what that means is Warrens efforts to remove all this before she officially becomes a presidential candidate – she is in the exploratory committee phase now – has failed and failed.
Much of the presidential campaign introduces yourself to voters who do not know you. And the best way to do that is to tell them the story of your life – how to get to a place where you think you're best equipped to represent a nation of over 300 million people.
This back story is hopelessly compromised for Warren now. Every time she talks about growing up or her life before this presidential battle, it will kill the (ongoing) controversy over why she claimed to be Indians despite very bad evidence of this claim. She won't be able to escape it. It will be in every story of her past – and in the minds of most voters when they think about which candidate to support.
When Donald Trump is the US President, nothing in politics is impossible. So Warren could somehow put all this behind her and be nominated. But there is no doubt that her path to the democratic presidential election has grown considerably steeper since October last year. And the slope became even more pitched on Tuesday.
