FBI joins EPA in investigating Flint water crisis for criminal violations

FBI spokeswoman says agency's role is 'investigating the matter to determine if there have been any federal violations' in lead contamination of drinking water

The FBI is working with a multi-agency team investigating the lead contamination of Flint's drinking water, alongside Environmental Protection Agency investigators who can tackle criminal violations of federal environmental law, officials said on Tuesday.

Also on Tuesday, it was announced that Darnell Early, the state-appointed emergency manager for Flint when its water source was switched, will leave his current role in Detroit's troubled school district four-and-a-half months early.
