MINNEAPOLIS (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 explained his decision by stressing that he has been frequently tested for the virus.
