SHARM EL-SHEIKH, Egypt (AP) — John Kerry, the top U.S. envoy at this year's U.N. climate talks in Egypt, has tested positive for COVID-19, a spokesperson said late Friday night, another potential setback for negotiations that were already going into overtime with no result in sight.

"He is fully vaccinated and boosted and experiencing mild symptoms. He is working with his negotiations team and foreign counterparts by phone to ensure a successful outcome of COP27,†spokesperson Whitney Smith wrote in a statement late Friday.
