Joe Biden has issued Executive Orders mandating that masks must be worn in a wide variety of venues.
Under the executive order, Biden is directing departments and agencies under his jurisdiction “to immediately take action to require people in federal buildings or on federal lands, on-duty or on-site federal employees, and on-site federal contractors to wear a mask and maintain physical distance,” according to the White House.
But the order also requires masks on various modes of public transportation, including trains, airplanes and intercity buses. And it’s that provision, attorneys who have challenged mask mandates in the past say, that could be the most vulnerable to a legal challenge.
