Donald Trump On Elizabeth Warren: 'She's Got A Big Mouth'

She must be getting under his skin.

Sen. Elizabeth Warren (D-Mass.) must be getting under Donald Trump's skin: The presumptive GOP presidential nominee added "big mouth" to his list of favorite nicknames for the progressive darling at a press conference Thursday.

"She's a woman that's been very ineffective, other than she's got a big mouth," Trump said of Warren, who has been criticizing him heavily lately. 

Trump also called Warren "Pocahontas"-- a nickname he's used before, reviving a 2012 controversy over her claims that she had Cherokee heritage. While Warren could not prove that she has Native American ancestry, there is also no evidence that she benefited professionally from the claim. But Trump insinuated Thursday that she used it to get where she is now. 

"I don't know if you'd call it a fraud or not, but she was able to get into various schools because of the fact she applied as a Native American and probably able to get other things," he said. "I think she's as Native American as I am, OK?"

Asked if he would be willing to debate Warren, Trump said he would.

Warren is a huge problem for Trump. Every time she delivers a speech calling him a "small, insecure money-grubber," or writes a post about his "toxic stew of hatred and insecurity" on social media, it goes viral. She is, so far, the Democrats' most effective attack-dog against the New York real estate mogul. 

Every time Trump attempts to defend himself against the senator, something sexist or offensive tumbles out of his mouth. He tweeted earlier this month that he hopes Hillary Clinton chooses "goofy Elizabeth Warren" as his running mate, and then attacked them both for "shouting" -- a common criticism men have of female politicians. 

‘‘She gets nothing done, nothing passed," he said Wednesday. "She’s got a big mouth, and that’s about it. But they use her because Hillary’s trying to be very presidential. She’s stopping with the shouting, OK?’’
