WASHINGTON (AP) — The United States says it will keep existing COVID-19 restrictions on international travel in place for now due to concerns about the surging infection rate because of the delta variant. It was the latest sign that the White House is having to recalibrate its thinking around the coronavirus pandemic as the more infectious variant surges across the U.S. and a substantial chunk of the population resists vaccination. It was also a reversal from the sentiment President Joe Biden voiced earlier this month when he said his administration was “in the process” of considering how soon the U.S. could lift the ban on European travelers bound for the U.S.
