Both Bernie Sanders and Hillary Clinton have taken up the water crisis in Flint, Michigan. During a visit to Flint over the weekend, Clinton called the poisoning of Flint’s water “immoral.” Sanders called it a “humanitarian crisis.” The state of Michigan meanwhile has fired the head of the Department of Environmental Quality’s drinking water unit over the contamination. Liane Shekter Smith is the only state employee fired over the crisis to date. The lead poisoning in Flint’s water began after an unelected emergency manager appointed by Governor Rick Snyder switched Flint’s water supply to the corrosive Flint River. Governor Snyder has faced increasing calls to resign.
