House panel calls governor, EPA chief to testify on Flint

The Republican governor has come under heavy criticism for the Flint crisis, which occurred after a state-appointed emergency manager switched the city's water supply to the Flint River in 2014 to save money.

Flint is under a public health emergency after its drinking water became tainted when the city switched from the Detroit system and began drawing from the Flint River in April 2014 to save money.

In addition to Snyder and McCarthy, Chaffetz said he has called Susan Hedman, the EPA's former Midwest region chief, and Darnell Earley, who was the emergency manager for Flint when the source of water supply was changed.
