Warren's Twitter blast was the latest round in a fight with Trump, which started Tuesday night with her going after him over past comments he made looking forward to the housing market crash. Trump later called her a "total hypocrite" and said she profited from buying foreclosed housing.

"I helped family buy their homes and out-of-work construction worker relatives make a living. I’m proud of that," Warren said in a tweet, sharing a video of her Tuesday remarks against Trump.
