The deadly rise in COVID-19 cases across the U.S. is forcing state and local officials to adjust their blueprints for fighting the virus, with Republican governors adopting mask mandates — skeptically, in at least one case — and schools scrapping plans to reopen classrooms. The steps face blowback from those who question the science behind mask wearing and social distancing and fear the new restrictions will kill off more jobs and trample on their civil liberties. In Iowa, Gov. Kim Reynolds had pushed back against a mask mandate for months but imposed a limited one Tuesday, becoming the latest GOP holdout to change course on face coverings.
