The CDC said in a statement on Wednesday that it is its “continuing assessment that at this time an order requiring masking in the indoor transportation corridor remains necessary for the public health.”
The CDC said it will continue to monitor public health conditions to determine if a mandate would remain necessary. It said it believes the mandate is “a lawful order, well within CDC’s legal authority to protect public health.”
