President Joe Biden tested negative for Covid-19 but will continue to isolate, according to the White House.
Biden "continues to feel very well," White House physician Kevin O'Connor said in a memorandum on Saturday. Despite his negative antigen test, "in an abundance of caution, the president will continue his strict isolation measures pending a second negative test," O'Connor said.
O'Connor had previously warned of the potential for a rebound in positive test results, a phenomenon among a small percentage of patients who, like Biden, used the antiviral medication Paxlovid as part of their treatment.
