The FBI is part of a criminal probe into Flint's water crisis. A rep for the US Attorney's Office in Detroit tells the Detroit Free Press that federal prosecutors are "working with a multi-agency investigation team ... including the FBI, the US Postal Inspection Service, EPA's Office of Inspector General, and EPA's Criminal Investigation Division." The House Oversight Committee will hold its first hearing on the water issue on Wednesday, with EPA officials expected to testify, per Reuters. Darnell Earley, Flint's emergency manager in 2014, declined his invite, a congressional staffer tells the Free Press. (Erin Brockovich says Flint's problems are just the beginning.)
