Dayne Walling was the mayor of Flint from 2009 to 2015. Though Walling was an elected official, he had been stripped of most of his power by the time the city of Flint chose to switch its water source from the Detroit River to the Flint River. A state-appointed emergency manager, Natasha Henderson, was the one with the power to make decisions for Flint—decisions that were always aimed at cutting costs to the city’s budget. Walling and his office refused to accept any culpability in the water crisis or to stand by Mona and her team’s research at a critical juncture. He lost his bid for reelection in 2015 and was replaced by Karen Weaver.
