Chalk circles on the sidewalk indicate safe social distancing for demonstrators, Wednesday, May 20, 2020, in St. Paul, Minn., during an informational picket sponsored by the Minnesota Nurses Association along Smith Avenue, outside United Hospital. Nurses are asking for a say in worker protections, increased PPE resources with higher safety standards and an end to retaliation against workers who have tried to protect themselves from the COVID-19 virus. After picketing, they marched to the State Capitol to hear speakers. (Jeff Wheeler/Star Tribune via AP)
