Curious what his answer will be when questioned on it. He doesn't seem to be the person to answer "The results came back negative. I do not have coronavirus". If he tries to sidestep it by stating "I'm fine" or "Everything's good" then the speculation will begin.
Either way... despite his age and being overweight, he likely isn't a candidate to actually die. He'll have access to whatever he needs, 24/7.
Wait, you expect this President to be clear about something?
