Joe Biden’s press secretary has tested positive for Covid-19, one of the highest-ranking members of his administration to contract coronavirus.

Jen Psaki said she last saw the US president five days ago, and dropped out of the delegation to the G20 meeting in Rome and COP26 summit in Glasgow after members of her household tested positive for the virus on Wednesday. She and the president sat outdoors “more than six-feet apart, and wore masks” on Tuesday, Psaki added.

Biden, who at 78 is in a high-risk bracket, has been fully vaccinated with the Pfizer jab and received a booster shot late last month. He has so far met the Pope and European leaders including the UK’s Boris Johnson, France’s Emmanuel Macron and Italy’s Mario Draghi during his visit.
