In this May 2, 2012 photo, Democratic candidate for the U.S. Senate, Elizabeth Warren, speaks to reporters during a news conference while campaigning at Liberty Bay Credit Union headquarters in Braintree, Mass. Warren addressed questions on her claim of Native American heritage. Warren, a Harvard Law School professor who is running in Massachusetts against Republican incumbent Scott Brown, was listed as Native American in several law school directories. Warren has said that her "family lore" described Indian ancestors, and the New England Genealogy Association said it found indications that Warren had a Cherokee great-great-great grandmother, which would make her 1/32 Indian.
