Sen. Lindsey Graham (R., S.C.) announced Tuesday he would take a DNA test to find out if he had more Cherokee blood than Sen. Elizabeth Warren (D., Mass.).
Graham told "Fox & Friends" that he heard his grandmother was part Cherokee, so he would take the test and then reveal the results live on the show in a few weeks.
"You're going to find out in a couple weeks," Graham said. "I'm going to take this test ... I'm taking it, and the results are going to be revealed here. This is my Trump moment. This is reality TV."
Graham quipped he was "dying to know."
Warren drew mockery from conservatives after a test's analysis released Monday showed her Native American ancestor could go back as many as 10 generations and thus make her as as little as 1/1,024th Native American.
"I think I can beat her," Graham said.
Warren has taken heat for years for listing herself as Native American as a law professor at multiple universities, without being able to document said heritage. President Donald Trump has long derided her as "Pocahontas."
Graham joked at the end of the interview he would probably wind up being "Iranian."
"That would be, like, terrible," the hawkish lawmaker said.
Fox News host Brian Kilmeade quickly jumped in to say the Iranians were good people but had bad leaders.
Warren said last month she would take a "hard look" at running for president against Trump in 2020, and her aggressive move to put her ancestry controversy behind her seemed to be another sign she will take the plunge.
