Congress is holding its first hearing today on lead poisoning in the water supply of Flint, Michigan. The crisis began after an unelected emergency manager appointed by Republican Governor Rick Snyder switched the source of Flint’s drinking water to the corrosive Flint River. Flint’s former emergency manager, Darnell Earley, refused to testify at today’s hearing despite a subpoena. On Tuesday, Earley announced he was resigning from his current position as emergency manager of the Detroit Public Schools. We’ll have more on the story after headlines.
