Trump leaves hospital to greet supporters

Trump staged a drive-by photo-op Sunday in front of supporters gathered with flags and banners outside Walter Reed National Military Medical Center.

In a video on Sunday, the President said that he had learned a lot of interesting things about Covid-19 that he planned to share with the country.

"I learned it by really going to school. This is the real school. This isn't the let's read the book school and I get it. And I understand it," Trump said.

Including Friday, when Trump was flown to the hospital on Marine One, the US has recorded another 121,000 cases of Covid-19 and another 1,800 deaths.
