Former New Jersey Governor Chris Christie has urged Americans to take coronavirus “seriously” after spending days in intensive care with Covid-19. Mr Christie, a Trump administration ally, revealed on Thursday he had recovered from the disease. He was one of several virus cases confirmed at the same time as President Donald Trump in early October. The infections have been linked to a “superspreader event” at the White House. More than a dozen cases have been traced to the Rose Garden event on 26 September, including two senators, the White House press secretary and President Trump’s former counsellor Kellyanne Conway. All appear to have recovered. Mr Christie said he attended the event, a ceremony where Mr Trump formally announced his nomination of the conservative Judge Amy Coney Barrett for a Supreme Court vacancy, believing he had “entered a safe zone”.(BBC)…[+]
