A regional director with the US Environmental Protection Agency has resigned.
Susan Hedman's resignation is linked to the drinking water crisis in Flint, with the announcement coming down Thursday afternoon.
Senate Minority Leader Jim Ananich released a statement on Hedman's resignation.
"We've said since day one everyone at every level needs to be held accountable for whatever role they had in this crisis," he said. "It's unfortunate the legislature and state aren't moving nearly as swiftly as the federal government now appears to be."
On the EPA website it said the Hedman was appointed by President Barack Obama to be EPA Region 5 Administrator on Earth Day 2010.
She directed EPA operations in the six-state Great Lakes region that includes Illinois, Indiana, Ohio, Michigan, Wisconsin, Minnesota and the reservations of 35 federally-recognized tribes. She led a team of over 1,000 scientists, engineers, lawyers, environmental specialists and administrative staff in the Region 5 Office.
