Trump wears mask in public

US President Donald Trump wears a face mask in public for the first time, donning a dark mask with the presidential seal as he walks through the corridors of Walter Reed military hospital outside Washington to meet wounded veterans.

"I think when you're in a hospital, especially in that particular setting, where you're talking to a lot of soldiers and people that, in some cases, just got off the operating tables, I think it's a great thing to wear a mask," Mr Trump tells reporters.
