Michigan Gov. Rick Snyder on Friday defended how his office responded to an email flagging a potential link between a surge in Legionnaires' disease and Flint's water, saying an aide asked for further investigation but a state agency did not bring forward the issue again. The governor, who has come under criticism for not publicly disclosing the spike in Legionnaires' cases until 10 months later, told The Associated Press that his director of urban initiatives, Harvey Hollins, asked the Department of Environmental Quality to look into it after getting the March email.
