Trump, 74, wore a mask as he waved from the back seat of a black SUV that crawled in a caravan of vehicles in front of the Military hospital where he is being treated for COVID-19, while supporters waving Trump 2020 flags chanted "USA! USA!"
In a video posted on Twitter, Trump said he planned "a little surprise" for his fans gathered outside.
DONALD TRUMP: I also think we're going to pay a little surprise to some of the great patriots that we have out on the street. And they've been out there for a long time, and they've got Trump flags and they love our country. So I'm not telling anybody but you, but I'm about to make a little surprise visit.

Four more years! Four more years!
- Four more years!
- Mr. President! Oh, my gosh! I love you! [INAUDIBLE] there he is! There he is! There he is! God bless our president! I will die for him. I will die for that man, happily. I will die for him. Anybody want to mess with him, you mess with me first. He is a hero, that man.
