President Trump said Monday evening that he can no longer call Sen. Elizabeth Warren, D-Mass., "Pocahontas" because she does not have "enough Indian blood."

"A bad thing happened last week, because Elizabeth Warren was exposed as being a total fraud. And I can no longer call her Pocahontas, because she has no Indian blood," Trump told thousands gathered at a rally for Sen. Ted Cruz, R-Texas, Monday evening.

"I can't call her Pocahontas. She doesn't qualify. ... I've been saying it for a long time," Trump said. "I've been saying it for a year and a half. I said, 'I have more Indian blood than she does, and I have none.' I can't use the name Pocahontas, but if you don't mind, I will anyway. We got to keep her down."

Warren took a DNA test to prove that she had Native American ancestry, as she has claimed numerous times throughout her political and academic career.

Carlos Bustamante, a Stanford University geneticist, conducted the test, which Warren used to respond to Trump's "Pocahontas" taunt and his mockery of her previous claim to be a Native American while a professor at Harvard Law School in the 1990s. Warren's roll-out of the test results was widely seen as a sign that she is running for president in 2020.

Rather than using a commercial service to conduct her DNA test, Warren hired Bustamante, 43, who appears in the video explaining the test and in a scene in which the Massachusetts senator telephones his office and asks to speak with him. Warren received considerable criticism for the test, which found that her Native American heritage stretches back six to 10 generations, making her between 1/64th and 1/1024th Native American.
