Elizabeth Warren has gone on a Twitter rampage against Donald Trump this weekend--on Saturday morning, she started with a response to his vice presidential pick, Mike Pence, whom she referred to as a "perfect match" for Trump: "Two small, insecure, weak men who use hate & fear to divide our country."

.@realDonaldTrump & @mike_pence are a perfect match: Two small, insecure, weak men who use hate & fear to divide our country & our people. — Elizabeth Warren (@elizabethforma) July 16, 2016

Of COURSE @realDonaldTrump - a guy who calls women fat pigs & bimbos - picked a VP who is famous for trying to control women's bodies. — Elizabeth Warren (@elizabethforma) July 16, 2016

She also referred to Pence's legislation on the Religious Freedom Restoration Act, which was seen as a measure that would discriminate against LGBT citizens. He signed a revised version later that would ban such discrimination.

And OF COURSE @realDonaldTrump - a guy who "[doesn't] feel good" about marriage equality - picked a VP famous for LGBT discrimination. — Elizabeth Warren (@elizabethforma) July 16, 2016

She attacked the Republican platform, too -- "The @GOP platform says overturn marriage equality & it supports parents putting their LGBT children through conversion therapy. Disgusting," she tweeted.

Trump tweeted at Warren Sunday morning, accusing her of lying about her heritage, and he said she'd be nothing without that lie.

He dared Clinton to pick her as her running mate.

If Goofy Elizabeth Warren, a very weak Senator, didn't lie about her heritage (being Native American) she would be nothing today. Pick her H — Donald J. Trump (@realDonaldTrump) July 17, 2016

That spurred a renewed tweetstorm from Warren.

Nasty name-calling & lies about my family aren't going to shut me up, @realDonaldTrump. Is that really all you've got? — Elizabeth Warren (@elizabethforma) July 17, 2016

Pres Reagan's Solicitor General was the Harvard prof who hired me, @realDonaldTrump. He says your right-wing conspiracy theories are a lie. — Elizabeth Warren (@elizabethforma) July 17, 2016

It might blow your mind that a woman worked hard & earned a good job on her own, @realDonaldTrump, but it's not the 1800s. It happens. — Elizabeth Warren (@elizabethforma) July 17, 2016

She pointed to media stories on developments in the various Trump U lawsuits against the presumptive GOP nominee, like this one.

Late Sunday morning, she concluded, "You're nothing but a thin-skinned bully and a lousy, cheating businessman."
