Presumptive GOP nominee Donald Trump, referencing Sen. Elizabeth Warren (D-MA) as Pocahontas during his campaign rally Tuesday night, continued his criticism of the Massachusetts Senator on Twitter Wednesday.

Trump posted, “Goofy Senator Elizabeth Warren @elizabethforma has done less in the U.S. Senate than practically any other senator. All talk, no action!”

Warren, whose Twitter account shows she’s tweeted 90 percent of the time during the month of May about Trump, responded to Trump’s criticisms with a Twitter rant on Wednesday afternoon, posting:

Watch this video, @realDonaldTrump. Explain why you root for working people to fail. https://t.co/5tpKNIjVdt — Elizabeth Warren (@elizabethforma) May 25, 2016

Explain why you want to let Wall Street off the hook, @realDonaldTrump. https://t.co/5tpKNIjVdt — Elizabeth Warren (@elizabethforma) May 25, 2016

Explain why you don’t pay taxes that our country needs to keep us safe, @realDonaldTrump. https://t.co/5tpKNIjVdt — Elizabeth Warren (@elizabethforma) May 25, 2016

.@realDonaldTrump: I helped family buy their homes and out-of-work construction worker relatives make a living. I’m proud of that. — Elizabeth Warren (@elizabethforma) May 25, 2016

If @realDonaldTrump actually believes every stupid lie he reads on the Internet, we’re in for a truckload of trouble if he’s President. — Elizabeth Warren (@elizabethforma) May 25, 2016

Anytime someone calls out @realDonaldTrump, he replies with right-wing conspiracies & lies. It’s not presidential – & getting very old. — Elizabeth Warren (@elizabethforma) May 25, 2016

I fight for working families every day, @realDonaldTrump. You fight only for Donald Trump. — Elizabeth Warren (@elizabethforma) May 25, 2016

Fling as much mud as you want, @realDonaldTrump. Your words & actions disqualify you from being President – & I won't stop saying it. — Elizabeth Warren (@elizabethforma) May 25, 2016

Out of Warren’s 42 tweets in the month of May, she’s tweeted to or about Donald Trump 38 times.
