What Were Those "Mistakes" in Warren's Mealy-Mouthed "Apology" to Native Americans?

During a forum on Native American issues in Sioux City, Iowa, Democratic presidential candidate Elizabeth Warren "apologized" for "mistakes" with respect to claims of American Indian identity:


Like anyone who’s being honest with themselves, I know that I have made mistakes. I am sorry for harm I have caused. I have listened and I have learned a lot, and I am grateful for the many conversations that we’ve had together.


As you can see, Warren did not specify her mistakes for which she was apologizing. She did previously apologize for last fall's DNA test debacle and for identifying herself as an American Indian on her Texas bar registration card prior to launching her presidential campaign in February. If one is of generous disposition Warren might be referring to those previous apologies. But there's more.


Does her apology also extend to identifying herself as Native American because her maternal grandfather "had high cheekbones like all the Indians do,"? Does her apology extend to identifying herself as Native American so she could obtain employment at Ivy League schools? Is she apologizing for her opportunism? Is she apologizing for lying?


Warren's "apology" raises more questions than answers. As such I believe this will continue to be Warren's kryptonite. Should she share a debate stage with Tulsi Gabbard I suspect will Gabbard confront her on this issue? If she does will Warren be any more prepared with her than she was with the Breakfast Club back in May when Charlamagne tha God likened her to Rachel Dolezal? If she isn't then her numbers could fall like they have with Kamala Harris after Gabbard confronted her with record as California Attorney General.


Of course, a great deal of this is up to Native Americans themselves. If the Native American community at large is inclined towards forgiveness then further scrutiny probably won't damage Warren barring new information. But if Native Americans believe Warren is speaking with a forked tongue then all the apologies in the world won't save her.
