AUGUSTA, Maine (AP) Maine’s legislative session is already a month old, but lawmakers just now are coming to a consensus on what exactly constitutes a proper face covering.

Legislative leaders on Thursday settled upon several acceptable styles of face shields that can be worn as an alternative to traditional masks.

The meeting came amid concerns that some lawmakers aren’t taking the mask requirement seriously. A committee clerk already quit over coronavirus fears. Masks must be worn in legislative spaces, but lawmakers can take off their masks if they’re alone in an office.
