Medical authorities are challenging Donald Trump’s decision to greet followers in a drive-past outside the hospital where he is being treated for coronavirus (Covid-19).
There are companies the US president, who wore a mask, may have compromised 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”.
Questions remain over the seriousness of POTUS Trump’s illness after conflicting statements over the weekend.
Talking on media, White House chief of staff Mark Meadows said doctors would decide later whether the president could be released from Walter Reed hospital, near Washington, on Monday.
Mr. Meadows stated he had spoken with Mr. Trump earlier, and that his condition appeared to have developed overnight. The president was taken to hospital on Friday evening, hours after announcing he had tested positive for the coronavirus.
