Dude's been given dexamethasone.
That is given to only the sickest patients. In fact it is potentially harmful in non-severe cases.
By the way, a side effect is a feeling of hyperactivity and euphoria, which explains the pointless joyride yesterday.
Not to mention the Remdesivir & Regeneron,
Would the medical team of the POTUS give him such a potent cocktail of drugs not indicated for a mild case, just for the hell of it?
Dude is seriously ill, and photo-ops of him signing blank pieces of paper and scowling at an inactive speakerphone don't change that.
He's not being discharged Monday, nor Tuesday, nor anytime soon. He will get worse before / if he gets better.
