If they want change, Flint resident Melissa Mays said those gathered in the crowd at Saints of God Church in Flint they need to have their voices heard from the city all the way to Lansing and in Washington, D.C.

"I'm telling you: this was an epically bad decision," said Edwards of the switch from Detroit water to Flint river water, going back over information he discussed earlier Tuesday during a news conference at Flint City Hall.
