For Biden it was a long-awaited opportunity to highlight the success of the vaccination campaign he championed. The White House encouraged gatherings and fireworks displays all around the country to mark — as though ripped from a Hollywood script — the nation’s “independence” from the virus. The White House was not requiring vaccinations but was asking guests to get a COVID-19 test and to wear a mask if they are not fully vaccinated.
