He said, "Think about how far we've come from quiet streets to crowded parade routes waving American Flags."Biden added some words of caution as well, saying: Don't get me wrong. Covid-19 is not under threat. We all know that there have been powerful variants, such as the Delta variant.He urged Americans to be vaccinated again. Biden had established a goal for the nation to reach 70 percent vaccinations by the holiday. This goal was met but not reached.
