President Donald Trump insisted on Friday he would never put the United States into a coronavirus lockdown but said "time will tell" if another administration takes office in January and does so, the closest he has come to acknowledging that President-elect Joe Biden could succeed him. In his first public remarks since Biden last Saturday was widely projected the winner, Trump said he expects a coronavirus vaccine to be available for the entire population as soon as April, amid a crush of new infections that has pushed daily case counts to record highs. In broadcast remarks in the White House Rose Garden, Trump also appeared to acknowledge for the first time the possibility of an upcoming Biden administration, though he stopped short of conceding the race and did not mention his Democratic rival by name.
