Trump has repeatedly made baseless claims of voter fraud since the election.

Donald Trump has said "time will tell" who will be in the White House next year, in his first public address since his defeat was announced. It's the closest he's come to admitting that he lost the US presidential election but he did stop short of any sort of formal concession to president-elect Joe Biden. "I will not - this administration will not be doing a lockdown," Trump said. "Hopefully whatever happens in the future, who knows which administration it will be - I guess time will tell, but I can tell you this administration will not go to a lockdown." It marked a brief shift in tone from the president who has repeatedly, and without evidence, claimed voter fraud since the election and vowed to fight the result in the Supreme Court. Trump was speaking in the White House Rose Garden in a press conference about the effectiveness about Operation Warp Speed. He did not take questions from the assembled press. He promised a vaccine would ship in "a matter of weeks" to vulnerable populations, however the Food and Drug Administration in America has not yet granted approval for the vaccine. "As a result of Operation Warp Speed, Pfizer announced on Monday that its China virus vaccine was more than 90% effective," Trump said. "Pfizer said it wasn't part of Warp Speed, but that turned out to be an unfortunate misrepresentation." However, the pharmaceutical company has insisted it is not part of Operation Warp Speed and said it did not accept any money to develop tests or manufacture the vaccine.
