Trump paid tribute to fallen heroes Monday at Arlington National Cemetery and later Baltimore's historic Fort McHenry, and he was true to form -- no mask. He's made it clear ... he's not going to wear a mask in public -- as he put it, he doesn't want to give reporter that satisfaction -- but he was seen once at a Michigan Ford plant wearing a mask behind a curtain.

Meanwhile, Joe and his wife, Jill, ventured outside for the first time since the shelter-at-home orders were implemented and his presidential campaign came to a screeching halt. The former VP and Jill laid a wreath during a visit to a veterans memorial in Delaware.

Joe, Jill and even his secret service detail all wore black masks.

Although a mask is a scientifically-based precaution, it's also become a political symbol. Trump clearly is telling his supporters NOT to wear them ... almost as if it's a sign of weakness. Biden clearly begs to differ.
