Sen. Lindsey Graham, R-S.C., is ready to show up Sen. Elizabeth Warren, saying Tuesday he plans to take a DNA test to find out whether he has more Native American heritage than she does.

“I’m going to take a DNA test,” Graham told “Fox and Friends” on Tuesday. “I’ve been told my grandmother was part Cherokee Indian. It may all just be talk.”

Graham said he would reveal the results on the show in a couple weeks.

“This is my Trump moment. This is reality TV,” Graham quipped.

Graham said he did not think much about his heritage until Warren released her DNA results concluding she may be between 1/1024 and 1/64 Native American.

“I’m dying to know,” Graham said. “I think I can beat her.”

President Trump goaded Warren, D-Mass., into taking a DNA test after months of mocking her ancestry claims. Earlier Tuesday, Trump called the results “phony” and demanded she apologize “for perpetrating this fraud” against Americans.
