Donald Trump on Friday retaliated against Elizabeth Warren on Twitter, sparking a social-media brawl between the pair.

The presumptive Republican nominee fired off a series of tweets three days after the Democratic Massachusetts senator called Trump narcissistic and racist on her own Twitter account.

A minute later, Trump jabbed Warren about her heritage, arguing she’s not part Native American. (Warren has defended herself amid the controversy that surfaced during her 2012 Senate bid.)

Let’s properly check goofy Elizabeth Warren’s records to see if she is Native American. I say she’s a fraud! — Donald J. Trump (@realDonaldTrump) May 6, 2016

Goofy Elizabeth Warren, Hillary Clinton’s flunky, has a career that is totally based on a lie. She is not Native American. — Donald J. Trump (@realDonaldTrump) May 6, 2016

Later Friday, Warren hit back on Twitter, calling Trump's response "lame."

I called out @realDonaldTrump on Tuesday. 45 million saw it. He's so confident about his "counter punch" he waited until Friday night. Lame. — Elizabeth Warren (@elizabethforma) May 7, 2016

“Goofy,” @realDonaldTrump? For a guy with "the best words" that’s a pretty lame nickname. Weak! — Elizabeth Warren (@elizabethforma) May 7, 2016

We saw when Scott Brown attacked my family & his staff made tomahawk chops & war whoops. They lost big. MA voters knew better. — Elizabeth Warren (@elizabethforma) May 7, 2016

We saw what happened when birthers like @realDonaldTrump attacked @BarackObama. They lost big. American voters knew better. — Elizabeth Warren (@elizabethforma) May 7, 2016

.@realdonaldtrump is a bully who has a single play in his playbook -- offensive lies thrown at anyone who calls him out. — Elizabeth Warren (@elizabethforma) May 7, 2016

.@realDonaldTrump spews insults and lies because he can’t have an honest conversation about his dangerous vision for America. — Elizabeth Warren (@elizabethforma) May 7, 2016

But here's the thing. You can beat a bully -- not by tucking tail and running, but by holding your ground. — Elizabeth Warren (@elizabethforma) May 7, 2016

If you think recycling Scott Brown's hate-filled attacks on my family is going to shut me up, @realDonaldTrump, think again buddy. Weak. — Elizabeth Warren (@elizabethforma) May 7, 2016

The @GOP's hate-filled lies didn’t scare me before, @realDonaldTrump. And they don't scare me now. — Elizabeth Warren (@elizabethforma) May 7, 2016

.@realDonaldTrump lied his way through the primaries without being held accountable. That’s over. — Elizabeth Warren (@elizabethforma) May 7, 2016

Whatever @realDonaldTrump says, we won't shut up. We won't back down. This election is too important, & he won’t step foot in White House. — Elizabeth Warren (@elizabethforma) May 7, 2016

Warren tweeted three days ago that Trump's campaign is built on “racism, sexism, and xenophobia” after he won Indiana's primary, and that “There's more enthusiasm for @realDonaldTrump among leaders of the KKK than leaders of the political party he now controls.”
