Donald Trump says he is 'immune' from coronavirus to sceptical response
The White House doctor has said the president is not considered a transmission risk, without declaring that he had tested negative for the virus.
US President Donald Trump says he is doing well, but that the next few days will be the "real test".
The video, posted on Twitter on Saturday evening, comes after mixed messages earlier in the day about his health, after a Covid-19 diagnosis.
The president's physician said late on Saturday that Mr Trump was doing well and had made "substantial progress since diagnosis".
Mr Trump is spending his second night in hospital.
Dr Sean Conley said in a statement that "while not yet out of the woods, the team remains cautiously optimistic" about the president's condition.
A few hours earlier, in the four-minute video message, Mr Trump, dressed in a suit jacket and shirt with no tie, thanked the doctors and nurses at the Walter Reed National Military Medical Center close to Washington DC, where he is being treated. #US President Donald #Trump said on Sunday he had fully recovered from #Covid-19 and was not an infection risk for others, freeing him to return to holding big campaign rallies during the final weeks of the race for the White House. Trump also said, without producing evidence, that he was now immune, a claim that drew a flag from Twitter for violating the social media platform's rules about misleading information related to Covid-19. U.S. President Donald Trump says he hasn't selected who he will nominate for the Supreme Court's vacant seat, but that he is looking to put forward the name of a female judge. Donald Trump has said he is starting to feel "much better" but the next few days will be "the real test" of his treatment for COVID-19.
In a video posted during his stay in hospital near Washington DC, the US president said that he was "starting to feel good" and was looking forward to "finishing up the (election) campaign the way it was started".
Speaking from his room at Walter Reed Military Hospital in Maryland, a tired-looking Mr Trump said: "I came here, wasn't feeling so well, I feel much better now."
