With the airplane mask mandate set to expire next week, President Joe Biden’s new coronavirus czar on Monday raised the possibility that the U.S. Centers for Disease Control and Prevention could once again extend the federal masking requirements for public transportation.

“This is a CDC decision and I think it is absolutely on the table,” White House COVID-19 response coordinator Dr. Ashish Jha told NBC News’ Savannah Guthrie on “Today.”

Jha said that the CDC is developing a “scientific framework” to guide its decision making and that agency director Dr. Rochelle Walensky will make a decision on the mask mandate for planes, trains, buses, and other means of public transportation within the week.
