evidence: What It Means When Trump Doesn't Wear A Mask [...] On Wednesday, Speaker of the House Nancy Pelosi, D-Calif., could not have been more emphatic. The president, she said, should wear a mask in public (as she does) to set an example for the public. [...] Trump first addressed the notion of a mask a month ago ("I don't think I'm going to be doing it") when the Centers for Disease Control and Prevention recommended the practice. This week he left Washington to tour, of all things, a Honeywell mask-manufacturing site in Phoenix. Once there, he wore protective goggles over his eyes — but no mask.
