Cedar Rapids Gazette: Cedar Rapids Mayor Brad Hart signed an emergency proclamation Wednesday requiring that face masks be worn in public as a measure to curb the spread of the coronavirus as Iowa is among the states leading the nation in the number of cases per capita. Cedar Rapids joins five other Iowa cities with mask mandates — Des Moines, Iowa City, Dubuque, Mount Vernon and Muscatine — as municipalities push back on state officials’ stances that local governments lack the legal authority to issue such mandates.
