Warren goes nuclear on Trump: You won't 'shut us up'
"We get it, @realDonaldTrump: When a woman stands up to you, you’re going to call her a basket case. Hormonal. Ugly," Warren tweeted.
"Do you think you're going to shut us up, @realDonaldTrump?" she asked in another tweet, one of several. "Think again. It's time to answer for your dangerous ideas."
"Your policies are dangerous. Your words are reckless. Your record is embarrassing. And your free ride is over."
The barrage of tweets directed at Trump came after the presumptive GOP nominee reiterated his attack on her as "goofy" and accused her of getting "nothing" done in the Senate.
The two sparred last week in a series of social media attacks, with Trump claiming he wanted Warren to be Clinton’s VP because it would hurt the Democratic ticket.
