The Biden administration is reportedly weighing whether to formally urge vaccinated Americans to once again mask up as the country experiences an increase in the number of COVID-19 delta variant cases. 

White House aides are in talks with officials at the Centers for Disease Control and Prevention (CDC) about proposed messaging to the public, the Washington Post reported. 

People familiar with the discussions told the Post that the White House is hesitant to implement policies that would explicitly mandate people show proof of their vaccination status. One idea reportedly thrown around was to ask Americans to wear masks when vaccinated and unvaccinated people not to congregate in crowded places.
