Medical experts are questioning Donald Trump’s decision to greet supporters in a drive-past outside the hospital where he is being treated for Covid-19.
There are concerns the US President, who wore a mask, may have endangered secret service staff inside the car.
White house spokesperson Judd Deere said the trip on Sunday had been “cleared by the medical team as safe”.
The president has been in hospital since Friday, after he announced hours earlier he had tested positive for the virus.
Meanwhile, NBC news reports that Melania Trump, who has remained at the white house with mild symptoms, decided against visiting her husband in hospital because of the risks to staff. It emerged the president’s condition was more serious than previously reported when he went to hospital on Friday evening.
