“I think this is every parent’s worst nightmare,” said Gov. Gretchen Whitmer, who added that shootings at schools are “a uniquely American problem that we need to address.”

“My heart goes out to the families. This is an unimaginable tragedy. I hope we can all rise to the occasion and wrap our arms around the families, the affected children and school personnel and this community,” Whitmer said.
