Elizabeth Warren and Donald Trump are going at it — again.

On Wednesday, the presumptive Republican nominee began attacking Warren (whom he calls “goofy”) on Twitter.

In the tweets, Trump brought up controversies that dogged the Massachusetts Democrat’s 2012 Senate campaign.

Trump’s line that Warren is “sometimes known as Pocahontas” is a reference to a controversy where she struggled to prove her Native American ancestry during the campaign. And the accusation that she “bought foreclosed housing and made a quick killing” is based off a Boston Herald report from 2012 which, among other things, said Warren had purchased foreclosed properties for cheap.

"Senator Warren and her husband Bruce are fortunate to be in a position where they have been able to help relatives buy their homes and in some cases make a living by fixing up houses and managing rental properties,” Warren’s press secretary, Lacey J. Rose, told USA TODAY in a statement Wednesday when asked about Trump's remarks.

Later Wednesday Warren had some thoughts to share about Trump's attacks as well:

Trump’s comments come in response to renewed attacks from the Massachusetts Democrat. On Tuesday night, Warren devoted 10 consecutive minutes during a speech at a gala at the Center for Popular Democracy railing against Trump.

Warren attacked Trump over saying that he was “excited” and “sort of hope(d)” the housing bubble would burst in 2006 and 2007.

“The rest of us were horrified by what happened during the 2008 financial crisis, by what happened to millions of families … but Donald Trump was drooling over the idea of a housing meltdown because it meant he could buy up more property on the cheap,” Warren said. “What kind of a man does that? What kind of a man roots for people to get thrown out of their house? … I’ll tell you exactly what kind of a man does that — it is a man that cares about no one but himself. A small, insecure, money grubber who doesn’t care who gets hurt so long as he gets a profit of it”

“A man who will never be president of the United States,” she added.

On Tuesday, the Clinton campaign posted a video featuring the remarks and Trump responded by defending his comments — saying he’s made a lot of money in bad markets.

Warren has stayed neutral in the Democratic primary fight between Clinton and Bernie Sanders.
