Massachusetts Senator and Democratic presidential candidate Elizabeth Warren was confronted by a voter over he past claims of Native American heritage, and responded by saying she “shouldn’t have done it,” and reiterating that she is “not a person of color.”

Warren took questions during a town hall meeting at a bowling alley in Petersborough, New Hampshire, including one from a voter who asked “What do I say to my native american relatives regarding the confusion around the native american ancestry issue?”

“I grew up in Oklahoma, and my three older brothers and I learned about our family same way most people do, from our mom and from our dad,” Warren explained, adding “My family is very important to me, and that’s why many years ago I sometimes identified as Native American.”

“Boston Globe did a big investigation about this, gosh what about a year and a half ago, never had anything to do with any job I ever got or any benefit,” she continued. “But even so, I shouldn’t have done it. I am not a person of color, I am not a citizen of a tribe, and I have apologized for confusion I’ve caused on tribal citizenship, tribal sovereignty, and for any harm that I’ve caused.”

Politico’s Alex Thompson tweeted video of Warren’s reply in two parts:
