WASHINGTON (AP) — President Joe Biden is dispatching the nation’s top scientists and public health experts to regularly brief the American public about the pandemic that has claimed more than 425,000 U.S. lives. Beginning Wednesday, the experts will host briefings three times a week on the state of the outbreak and efforts to control it. Americans can expect a sharp contrast from the Trump administration’s briefings, when public health officials were repeatedly undermined by a president who shared his unproven ideas without hesitation. Wednesday’s briefing will feature the Biden administration’s coordinator for pandemic response, as well as government scientists and public health officials.
