It looks like Donald Trump's feud with Sen. Elizabeth Warren, D-Mass., isn't over yet.
According to the New York Times' Maureen Dowd, the presumptive Republican presidential nominee has taken another jab at Warren, again calling attention to a long-running controversy over whether Warren has Native American ancestry.
"When I asked if he had been chided by any Republicans for his Twitter feud with Elizabeth Warren, he replied, 'You mean Pocahontas?'" Dowd wrote in her Sunday column. "So much for reining it in."
On March 20, Trump also attacked Warren, a former Harvard Law School professor, telling the Times, "I think it’s wonderful because the Indians can now partake in the future of the country. She’s got about as much Indian blood as I have. Her whole life was based on a fraud. She got into Harvard and all that because she said she was a minority."
Warren fired back the next day, tweeting that Trump has been able to keep his father's empire going by using corporate bankruptcies to get rid of debt. She also wrote that experts say Trump might have more money if he had just left his inheritance in an index fund.
Their back-and-forth resurfaced earlier this month when Warren tweeted that Trump "built his campaign on racism, sexism and xenophobia."
A few days later, Trump tweeted, "Goofy Elizabeth Warren, Hillary Clinton's flunky, has a career that is totally based on a lie. She is not Native American."
Warren replied, "'Goofy,' @realDonaldTrump? For a guy with 'the best words' that's a pretty lame nickname. Weak!"
