ROCHESTER, Minn. (AP) _ Vice President Mike Pence chose not to wear a face mask while touring the Mayo Clinic in Minnesota.

It's an apparent violation of the world-renowned medical center's policy requiring them.

Video feeds show he didn't wear a mask when he met with a Mayo employee who has recovered from COVID-19. He was also maskless when he visited a coronavirus testing lab.

And Pence was the only participant not to wear a mask during a roundtable discussion.

Food and Drug Administration chief Stephen Hahn was among those wearing masks. Pence's office did not immediately respond to a request for comment.
