There are blue eyed blonde Lakota Sioux too. She probably claimed her minority status to get a free college education. Like many Indians, there appears to be no proof that she can verify. Sounds like she has a good con game going and if she is running for Senate now, maybe she should run for President.
Sorry your prejudicial fantasies don't hold up... Warren attended George Washington University on a debate team scholarship. She finished her undergrad work at the University of Houston. No mention of minority status.
