“The governor of this state should understand his dereliction of duty was irresponsible. He should resign,” Vermont Sen. Sanders said, a call he has made before.

Then former Secretary of State Clinton agreed, the first time that she has said Snyder should resign over the lead in Flint’s water. “The governor should resign or be recalled, and we should support the efforts of citizens to achieve that,” she said.

Snyder took to Twitter during the debate to defend himself:

Sanders connected the water crisis back to his favorite topic on the stump: income inequality. “We need to rebuild our crumbling infrastructure,” he said. “Our water systems, our waste water plants, our roads and our bridges. The wealthiest country in the history of the world has got to get its priorities right, take care of the people, no more tax breaks for billionaires.”

Clinton also said she would support consequences for public officials, and that she would launch an investigation into who knew about the water contamination, and when. “People should be held accountable, wherever that leads,” she said.

Both candidates were met with loud cheers from the Flint audience.
