"I hope corrupt Hillary Clinton chooses goofy Elizabeth Warren as her running mate. I will defeat them both," Trump tweeted

Shortly after Trump's latest salvo Friday night, Warren fired back some shots of her own.

Washington CNN —  

Donald Trump took to Twitter Friday evening to pile criticism on Massachusetts Sen. Elizabeth Warren, who earlier in the week had condemned the presumptive GOP nominee as a racist.

Trump began Friday, “I hope corrupt Hillary Clinton chooses goofy Elizabeth Warren as her running mate. I will defeat them both.”

He continued: “Let’s properly check goofy Elizabeth Warren’s records to see if she is Native American. I say she’s a fraud!”

Next, he tweeted, “Goofy Elizabeth Warren, Hillary Clinton’s flunky, has a career that is totally based on a lie. She is not Native American.”

Trump was referring to a controversy surrounding Warren that emerged during her successful 2012 Senate bid over her past claims about having Native American ancestry. At the time, her Republican challenger, Scott Brown, demanded she provide documented proof, but Warren said her heritage had been passed down in words, not on paper.

Friday’s tweet storm isn’t the first time Trump has responded to Warren in this fashion. Asked in March about attacks the Massachusetts senator had made on him, Trump responded, “Who’s that, the Indian?”

Earlier in the week, Warren went on a Twitter tirade against the Manhattan billionaire, saying he had “built his campaign on racism, sexism and xenophobia.”

And shortly after Trump’s latest salvo Friday night, she fired back some shots of her own.

“‘Goofy,’ @realDonaldTrump? For a guy with ‘the best words’ that’s a pretty lame nickname. Weak!” Warren tweeted.

She added, “If you think recycling Scott Brown’s hate-filled attacks on my family is going to shut me up, @realDonaldTrump, think again buddy. Weak.”

The progressive senator has regularly been floated as a potential running mate for the eventual Democratic nominee, regardless of who it is. Bernie Sanders mentioned Warren by name in response to a question about a possible vice president, and she is also presumed by many to be a potential Clinton choice.
