A Republican running against Sen. Elizabeth Warren in Massachusetts said he's ready to challenge her anti-Trump platform and claims of Native American ancestry.

Shiva Ayyadurai is an Indian-American running for the Republican Senate nomination. He was interviewed on Fox Business about running for Warren's seat in 2018.

"Well, I think only a real Indian can defeat a fake Indian," he said.

Warren has previously claimed to have Native American heritage, though reports say she could only be about 1/32 Native American.

"I sent her a DNA test kit for her birthday, and I was very sad that she returned it," Ayyadurai added.

Ayyadurai said he's a big supporter of President Trump, unlike Warren, who has been vocal in her criticism of the administration.

"I love Donald Trump, I think he's doing a great job," Ayyadurai said. "He's my hero."
