Michigan Lt. Governor Brian Calley declined to answer questions about calls for Governor Rick Snyder to resign.
Democrats say the Republican governor should step down because of his handling of the Flint water crisis.
If he did, Calley would become governor.
In Flint today, Calley declined to speculate on Snyder resigning.
“I know the governor is completed committed to seeing this through,” he said.
The Michigan Republican Party attacked Democratic calls for Snyder to resign, saying they should “put aside politics” and focus on helping people in Flint.
