US Senate candidate Elizabeth Warren - who said Friday she didn’t realize Harvard Law School had been promoting her as a Native American faculty member in the 1990s - was listed as a minority professor in American law school directories for nine years before she landed at Harvard, documents show.The Association of American Law Schools desk book, a directory of law professors from participating schools, includes Warren among the minority law professors listed, from 1986 through 1995. The listings were based on professors reporting that they were members of a minority group, the directory says.
