Sen. Elizabeth Warren on Wednesday prompted a new fight with the presumptive GOP presidential nominee on Twitter.

We get it, @realDonaldTrump: When a woman stands up to you, you're going to call her a basket case. Hormonal. Ugly. — Elizabeth Warren (@elizabethforma) May 11, 2016

Warren asked if it's true that Trump wants to abolish the federal minimum wage, but then Trump later said she "lied" when she said that, and suggested he would ask for an increase.

The Massachusetts Democrat also asked if he "raked in millions scamming students with Trump University" and if he would "absolutely" repeal the Wall Street reform law Dodd-Frank.

.@realDonaldTrump: Your policies are dangerous. Your words are reckless. Your record is embarrassing. And your free ride is over. — Elizabeth Warren (@elizabethforma) May 11, 2016

Trump responded, calling her an "ineffective senator" and "goofy."

He also mocked her claims to Native American heritage.

Our Native American Senator, goofy Elizabeth Warren, couldn't care less about the American worker...does nothing to help! — Donald J. Trump (@realDonaldTrump) May 11, 2016

Isn't it funny when a failed Senator like goofy Elizabeth Warren can spend a whole day tweeting about Trump & gets nothing done in Senate? — Donald J. Trump (@realDonaldTrump) May 11, 2016

It's the second time in the last week that the two have fought on Twitter.

In an interview with Mic, Warren declined to say whether she would consider being Hillary Clinton's running mate in the general election.

"I love my job. I'm here in the United States Senate doing exactly what the people of Massachusetts sent me here to do," she said when asked if she would consider serving as Clinton's vice president.
