I understand the sentiment, but if you’re really sick with something affecting your cardio-pulmonary system, you’re not going to be walking normally. Thing is, as we know, C19 affects different people differently. The onset of symptoms can be gradual or as sudden as an avalanche.I'm less inclined at this point to believe anything positive regarding how Trump presents himself in public. He wants to look healthy while the cameras are pointed at him. I'm pretty sure he's been instructed as such by his team.
So it’s possible Trump walked into the hospital normally, and a few hours later, be experiencing some alarming symptoms.
