Vaccinated Nancy Pelosi wears a mask with inoculated colleagues, but not when she got a blow-out

With the world watching, a fully-vaccinated House Speaker Nancy Pelosi (D-CA) wore a mask during the entirety of President Joe Biden's first joint address to Congress on Wednesday.

Guidance  from the Centers for Disease Control and Prevention states that while indoors, unvaccinated Americans should wear masks. However, it states that those who have been vaccinated, like Pelosi, "can gather indoors with fully vaccinated people without wearing a mask or staying 6 feet apart." Despite this guidance, Pelosi sat masked, next to Vice President Kamala Harris, who is vaccinated, while Harris was also masked.
