Gliding over significant challenges still to come, President Donald Trump offered a rosy update on the race for a vaccine for the resurgent coronavirus as he delivered his first public remarks since his defeat by President-elect Joe Biden. He still did not concede the election.

Refusing to concede a presidential election he lost, President Donald Trump sought falsely to take full credit for drugmaker Pfizer Inc.’s announcement that its COVID-19 vaccine may be 90% effective, wrongly asserted the vaccine news was delayed until after Election Day to undermine him and repeated baseless claims of voter fraud.
