DETROIT (AP) — A judge says a class-action lawsuit against Michigan and Flint officials stemming from the city’s lead-contaminated water crisis can proceed but has dropped Gov. Rick Snyder and others from the case.

U.S. District Judge Judith Levy ruled Wednesday that the suit filed on behalf of residents and businesses didn’t claim Snyder knew of risks when the city switched to Flint River water in 2014. The corrosive water caused lead to leach from old plumbing.
