Subpoenas for records were served to Gov. Rick Snyder, the governor's office and the Michigan Department of Environmental Quality on Jan. 25. The records include emails, text messages or other documents sent or received by Snyder, his staff, or the emergency managers Darnell Early, Michael Brown, Gerald Ambrose or Edward Kurtz relating to the Flint River as a water source from Jan. 1, 2011 to the present. One of the lawsuits was filed in a federal court in November.
