WASHINGTON — Sen. Elizabeth Warren, D-Mass., attacked Donald Trump's economic policies on Twitter Wednesday, including his call to repeal the Dodd-Frank Act.

While Trump has successfully dodged laying out clear policy goals, the exchange on Twitter clearly got under the New York businessman's skin and may force him to provide a few more specifics ahead of the general election.

The exchange was first instigated by Trump, who called Warren "goofy" in an early-morning tweet. Warren responded with her own tweetstorm in which she referenced his views on Dodd-Frank:

Trump responded to Warren by repeatedly dubbing her "Goofy Elizabeth Warren" and then tweeting about her views throughout the rest of the day. Among other things, he accused her of being "ineffective" and said she didn't run for president because she is unelectable.

However, it was Warren's tweets on Trump's positions on the minimum wage that could shed some light on the Massachusetts Democrat's strategy.

That tweet garnered this response from Trump.

Perhaps the strangest attack that Trump launched against Warren was accusing her of not doing her job because she was spending so much time on Twitter.

The allegation is ironic, to say the least, considering Trump's prevalence on Twitter and his own multi-hour attacks on the senator.
