Des Moines Register: Masks are now a must in Des Moines city buildings, and some officials want a broader mandate requiring face coverings in all public spaces. The Des Moines City Council unanimously passed a resolution on Monday requiring members of the public and city employees to wear face coverings such as masks or shields inside city buildings. The resolution also urges other entities, including city contractors, nonprofits and businesses, to enforce similar rules based on guidelines from the Center for Disease Control and Prevention.
