New York Gov. Andrew Cuomo is demanding that the federal government ban or require testing of travelers from Britain—which locked down London and other areas after a fast-spreading variant of COVID-19 was identified. “Right now, this variant in the U.K. is getting on a plane and flying to JFK,” Cuomo told reporters on Sunday, according to the New York Post. “Literally six flights a day. And all it takes is one person.” Belgium, Canada, and several other nations have halted flights from the U.K. because of the variant—which has already made its way to Italy.
