U.S. health officials on Tuesday, May 3, reinstated their recommendation that Americans wear masks on planes, trains and buses, despite a court ruling last month striking down a national mask mandate on public transportation.

The government repeatedly extended the mandate, and the latest one had been set to expire May 3, but a federal judge in Florida struck down the rule on April 18. The same day, the TSA said it would no longer enforce the mandate.
