My guess is she got the ball rolling and the universities perhaps promoted her more than she did herself (but she maybe didn’t ask any questions and didn’t do much to correct the record). So a mixed bag. But there’s enough there that she felt compelled to make that weird video that just made the issue worse. From Snopes:
“The legitimacy of Warren’s claims to Native American heritage has certainly been challenged by many critics, and it is true that while Warren was at U. Penn. Law School she put herself on the “Minority Law Teacher” list as Native American) in the faculty directory of the Association of American Law Schools, and that Harvard Law School at one time promoted Warren as a Native American faculty member. But specific evidence that she gained her position at Harvard (at least in part) through her claims to Native American heritage is lacking. Warren denied applying for special consideration as a person of Native American heritage during her career, and when the matter was examined in 2012 in response to Brown’s claims, people with whom Warren had worked similarly denied her ancestral background’s factoring into the professional opportunities afforded her:
The former chairman of the American Association of Law Schools, David Bernstein, told the Herald that the group’s directory once served as a tip sheet for administrators. “In the old days before the Internet, you’d pull out the AALS directory and look up people,” he said. “There are schools that, if they were looking for a minority faculty member, would go to that list and might say, ‘I didn’t know Elizabeth Warren was a minority.'”Warren said she didn’t know Harvard had used her heritage as proof of diversity until reading about the issue in the news, according to a Herald report. She also denied that she ever tried to gain a professional advantage through her lineage.
Warren responded she was recruited for the positions and did not “apply” for them; and for the most part, her record did not indicate any identification as part of a minority group:
The Globe obtained a portion of Warren’s application to Rutgers, which asks if prospective students want to apply for admission under the school’s Program for Minority Group Students. Warren answered “no.”For her employment documents at the University of Texas, Warren indicated that she was “white.”
But Penn’s 2005 Minority Equity Report identified her as the recipient of a 1994 faculty award, listing her name in bold to signify that she was a minority.
The Herald has twice quoted Charles Fried, the head of the Harvard appointing committee that recommended Warren for her position in 1995, saying that the Democratic candidate’s heritage didn’t come up during the course of her hiring. “It simply played no role in the appointments process,” he said. “It was not mentioned and I didn’t mention it to the faculty.”
The Herald later quoted Fried, a former U.S. Solicitor General under President Ronald Reagan, saying, “I can state categorically that the subject of her Native American ancestry never once was mentioned.”
