US President Joe Biden tested negative for COVID-19 on Saturday but will continue to isolate at the White House until a second negative test, his doctor said. Dr. Kevin O’Connor wrote in his latest daily update that the president, “in an abundance of caution,” will abide by the “strict isolation measures” in place since his “rebound” infection was detected July 30, pending a follow-up negative result. Biden’s travel has been on hold as he awaited a negative test. He plans to visit Kentucky on Monday to view damage from catastrophic flooding and meet with families, reports AP. — Agencies
