Vice President Mike Pence said it's up to state and local governments to issue guidance and orders on face masks.
Asked if he had a message to Americans about the importance of wearing masks, Pence said "people ought to listen to their state and local authorities."
While a handful of states require people to wear masks in public, many others have not issued any guidance. Some individual cities and counties have also issued orders to require facial coverings.
Pence said he's in contact with many state and local leaders, and said he's assured them that he will urge Americans to follow local directives.
"In some cases, there's statewide guidance with regard to facial coverings and with regard to events and gatherings. In other cases, there's specific county-wide or city-wide directives, and we just believe that what's most important here is that people listen to the leadership in their state, the leadership in their local community, and adhere to that guidance," Pence said.
Face masks — which has been proven to be an effective way to stop person-to-person spread of coronavirus — has become a contentious topic.
President Trump has been reluctant to wear a face mask in front of cameras, and the debate over their use has spilled into local communities. This week, residents of Palm Beach County in Florida erupted in anger at a commissioner's meeting after an unanimous vote to make masks mandatory.
