Donald Trump speaks at a rally on May 25 in Anaheim, Calif. | Getty Trump on 'Pocahontas' tweet: No regrets whatsoever

Donald Trump has no regrets about calling Sen. Elizabeth Warren “Pocahontas,” he said Friday.

"None whatsoever," Trump told NBC News when asked if he had any regrets about his comments.


"Pocahontas is at it again!" he tweeted Friday morning. "Goofy Elizabeth Warren, one of the least productive U.S. Senators, has a nasty mouth."

His latest "Pocahontas" attack comes after Warren delivered a blistering speech Thursday night, in which she called the presumptive Republican presidential nominee a "loud, nasty, thin-skinned fraud."

The Massachusetts Democrat responded to Trump via Twitter.

"No, seriously -- Delete your account," she said, echoing a viral line from Hillary Clinton, whom she endorsed Thursday evening.

In the past month, Trump has repeatedly referred to Warren as "Pocahontas," invoking the controversy surrounding Warren's assertion of Native American ancestry.

South Carolina Sen. Lindsey Graham, who blasted Trump's "un-American" remarks about the Indiana-born judge of Mexican descent presiding over class-action lawsuits against Trump University, said he didn't believe the Warren attack was racist.

"I thought it was funny," he told reporters on Friday, according to The Hill. "I think what he said about the judge was racist. When you're talking about a politician, you've got to be able to take a joke."

But the line isn't settling so well with certain advocacy groups.

Kitcki Carroll, executive director at United South and Eastern Tribes Sovereignty Protection Fund, told POLITICO that the organization expects all presidential candidates to engage in “respectful and diplomatic relationship with Tribal Nations.”

“Too often, we exist as a mere footnote in history. This often leads to issues of romanticizing, characterization, stereotyping, disrespect, and dishonor, for which there is no place and is unacceptable in the 21st century,” Carroll said. “We call upon the candidates to set the tone for an accurate, productive, and respectful national dialogue surrounding our Nations, our history, and our future.”
