Thanks for getting the original article. I followed links about Prof Greg Sarris and his claims about "discovering he was a Native American" and his quest to develop a casino and guess what?
There is a "Stop The Casino 101" web site that did research on his ancestry and from the evidence they found, HE IS A FRAUD.
The news media and Fiorina campaign should go viral with this because Boxer and her family have made millions from this fraud against the American people and true Native Americans.
Not that I am defending Greggy, but "mulatto" has been used in the past to also identify mixed Indian ancestry.
Why I don't know. I suppose some people found it "less undesirable" to be called mulatto. Or perhaps the person making the record thought it was more insulting if they did not like the person.
