Look, Im going to wear a mask on a plane for the rest of my life, even if I dont have to, replied the former Obama aide . Planes are gross, I think, just to begin with, she continued, echoing a point famously made by supermodel Naomi Campbell .

But I think they will. You are in close quarters. Im going to, Im just going to do it. Im just going to own it, Harf said.

What!? responded fellow panel member Guy Benson. Kennedy laughed.

Commentator Kat Timpf said shed done plenty of gross things without a mask on.

But I think they will. It makes everyone feel better, Harf argued. You dont know who is vaccinated and who isnt. So, mask up on planes.

Kennedy scoffed, saying she was going to wear caftans on every flight from now on.

All passengers on public conveyances, including airplanes, are required to wear a mask over their nose and mouth regardless of their vaccination status, per the Centers for Disease Control and Prevention .

Transportation Secretary Pete Buttigieg in May said wearing face masks on airplanes was a matter of safety, but its also a matter of respect.
