Donald Trump's been accused of putting his security team at risk by going for a surprise 'drive by' to greet supporters outside the hospital where he's being treated for coronavirus.
The President sat in an armoured SUV, waving to people as he was driven along the road. He was wearing a mask, but his motorcade was packed with other people.
A doctor at Walter Reed National Military Medical Center in Maryland has called the trip 'insanity'.
The trip came just moments after the President posted a video on Twitter claiming that he now 'understands' the virus.
Mr Trump's medical team say he may return to the White House later - but also say he's receiving steroid treatment.
