Ok this is the leader of the free world we're talking about here. Surely a sample is being isolated and analyzed in a lab right now to verify exactly what it is POTUS 'has'? If not, the 'treatment' they're giving him is what we used to call 'poke and hope'. Grasping at straws if you will.
I'm wondering where he's going with this, too. He's a wily one, our POTUS. He's exposing something, don't know what yet.
