President Joe Biden hosted a large, in-person event at the White House for the Los Angeles Dodgers, building up to a weekend billed by his administration as celebrating “independence” from the Covid-19 virus.

About 67% of adults in the U.S. have had at least one vaccine dose, enough for Biden to plan a victory tour even though he missed his target of reaching 70% by July 4 and U.S. health officials are raising alarm about the spread of the more-transmissible delta variant.
