Hillary Clinton and potential running mate Senator Elizabeth Warren hit the campaign trail together in Ohio on Monday and both took a jab at Donald Trump.

FOX’s Jill Nado has more:

Even before Democratic presidential hopeful Hillary Clinton and potential VEEP choice Senator Elizabeth Warren appeared together at a Cincinnati rally, republican Donald Trump sent out a tweet, calling Warren “goofy.”

The mudslinging didn’t stop there as Warren bashed Trump before the Ohio crowd:

(Warren) “He will crush you into the dirt to get whatever he wants.”

Clinton then taking the stage to praise Warren:

(Clinton) “I do just love to see how she gets under Donald Trump’s thin skin.”

Neither Trump or Clinton have made any formal announcements about their running mates, but both camps have been letting reporters know the lists are getting shorter and shorter.
