From a Politico article on the same story:

According to the Harvard law professor, she is 1/32nd Native American, and her campaign has maintained that Warren never leveraged her ethnic status to gain professional advantages.

re: #1 Ascher

Think of it this way: by claiming Warren as a minority faculty member, multiple parties were harmed.

These parties were harmed only if her claim to be part Native American is baseless. One shouldn’t jump to conclusions before the facts are clear.
