WASHINGTON: President Donald Trump is not yet on a clear path to recovery from Covid-19 and some of his vital signs over the last 24 hours were very concerning, a person familiar with his health said on Saturday.

The source's assessment of the Republican president's medical status came after a team of doctors told reporters at a press conference earlier on Saturday that he was "doing very well."

One of those doctors said Trump had told them "'I feel like I could walk out of here today.'"

The source, who asked not to be identified, said the next 48 hours will be critical in terms of Trump's care.
