Warren is going to ride that horse as long as possible. Someone needs to get a sample of her DNA and have it tested. !00 to 1 she HAS ZERO Mative American blood.
Unfortunately DNA testing may or may not show any links. She’s been a liar from the start but testing results depend on which side of the family she inherited the majority of her genes from.
My lineage shows mostly British Isles and Scandinavian ancestry from my father’s side of the family and my brother shows mostly western European, Swiss and German from my mother’s side.
It’s 50-50 whether she’d show much more than a single 400-year old marriage of a European ancestor to an Indian ancestor, depending on when her ancestors actually came here.
