Joe Biden addressed the nation for the first time as its 46th president on Wednesday. Biden spoke at a scaled-down event before a divided nation still reeling from the Jan. 6 riot at the U.S. Capitol and from the coronavirus pandemic that has now killed more than 400,000 Americans.

President Trump's medical team held a briefing with reporters at Walter Reed National Military Medical Center again on Sunday.
