Sanders and Warren have their gloves out — over the USMCA

Kathryn Krawczyk

A Sanders-Warren fight was in the forecast for Tuesday's Democratic debate, and a Sanders-Warren fight did happen.

But not much actually stemmed from when Sen. Bernie Sanders (I-Vt.) was asked about reportedly telling Sen. Elizabeth Warren (D-Mass.) a woman couldn't be president. Instead, the two progressives' biggest disagreement actually came from one of their biggest policy disagreements, over the United States-Mexico-Canada trade agreement.

Warren got a question about the USMCA first, and she reiterated her support for the bill that came out of the House with support from both Democrats and President Trump, calling it a "modest improvement" over the North American Free Trade Agreement it's set to replace. Yet Sanders challenged the compromise trade agreement, saying it doesn't take climate change into consideration despite it being "the greatest threat facing this planet."

Sanders did get a question about his alleged comments to Warren later in the debate, but he denied it ever happened, and Warren didn't exactly affirm that it did.
