I think this explains Mr. Trump’s pitiful attempt to look strong and resolute on the White House portico as he defiantly removed his mask and struck a defiant pose. Of course, the effect was ruined by the fact that he was very visibly fighting for every breath.
I think that defiant gesture is not playing the way he hopes. When he removed that mask and then entered the residence a lot of people saw a self-centered, science-denying jerk endangering the people around him. That is NOT a good look. IMHO.
