From WMATA:
“Effective immediately, Metro will make masks optional on Metrorail, Metrobus and MetroAccess for its customers. Masks also will be optional for Metro employees. This change comes as a result of the Transportation Security Administration (TSA) suspending enforcement, while the Biden Administration reviews a federal judge’s ruling.
“Our mask mandate has been based on federal guidance,” said General Manager and Chief Executive Officer Paul J. Wiedefeld. “We will continue to monitor this situation as it unfolds, but masks will be optional on Metro property until further notice.”
Metro encourages its customers to make decisions that are in their best interests. Updates will be provided as new information becomes available.”
