CNN announced early Sunday that it will host a debate between Democratic presidential candidates Hillary Clinton and Bernie Sanders next month in Flint, Mich., which has been hit hard by contaminated drinking water. The March 6 event will come two days before the Michigan and Mississippi primaries. The debate is part of a deal to schedule more DNC-sanctioned debates after the initial lineup was criticized. Clinton is expected to campaign in the city on Sunday while Sanders has called on the state’s governor, Republican Rick Snyder, to resign over the crisis. Three House hearings have been scheduled to examine the contamination, caused by lead from old pipes leaching into Flint’s water supply.
