Elizabeth Warren Is Ripping Into Donald Trump in Their Intense Twitter War

Over the weekend, likely GOP presidential nominee Donald Trump and Democratic Massachusetts Senator Elizabeth Warren got into a heated argument on Twitter. And now they're at it again.

It started this morning with a tweet from Trump, calling her "goofy Elizabeth Warren" and referring to her contested claim that she is Native American.

Warren responded with a series of tweets that addressed his treatment of women and the hypocrisies of his platform.

Trump fought back, of course, refusing to let go of the "goofy" nickname.

The tweets come the same day Trump nicknamed Bernie Sanders "crazy Bernie."
