Shiva Ayyadurai went on Fox Business’ Varney & Co Wednesday to talk about his campaign to replace Senator Elizabeth Warren in 2018, and he is sure confident about it.

Ayyadurai repeatedly bashed Warren, calling her a “self-serving elitist,” “un-American,” and a fake fighter.” But when it comes to how confident he is about beating her, it was his statement about his ethnicity that stole the show.

“I think only a real Indian can defeat a fake Indian,” Ayyadurai said. “I sent her a DNA test kit for her birthday and I was very sad she returned it. That’s the issue of a real Indian and a fake Indian, the truth, because there is a woman who actually checked off the box that she is Native American.”
