Biden Says Battle Against Coronavirus Needs Commander in Chief Steve Herman WHITE HOUSE - U.S. President-elect Joe Biden on Wednesday declared that the battle against COVID-19 "is like going to war. You need a commander in chief." Biden is to be sworn in as the 46th president, succeeding Donald Trump, on January 20. During a virtual roundtable discussion with front-line health care workers, whom he hailed as heroes fighting the coronavirus, Biden predicted: "I'll make mistakes. But I promise you I'll acknowledge them when I make them, as well as I'll take responsibility." Biden said when he gets into office, he will urge state governors to order mandatory masking, testing, tracing and social distancing. "I will be using the Defense Authorization Act. I will be using the bully pulpit," the president-elect said. "The words of a president matter." Biden also said it is important to find a way to get children back to school, as "they're going to be behind the curve," missing so much classroom time due to the pandemic. As the discussion was under way, New York City announced its public schools district, the largest in the country, would close to in-person learning, due to a rise in COVID-19 cases. The city reached the 3% positive testing threshold over a week, triggering the change, said Mayor Bill de Blasio. .
