God Bless Him! I hope they got him in time to provide treatment to mitigate some of the damage.
Amen to that. I know from family experience that everything depends on how soon the stroke victim receives treatment.
I don't know more than this: there is a special drug, which if administered within a window time of some three hours, can totally reverse the effects of the stroke. That being the case, Sen. Johnson's outlook appears OK. As well it should be. The OldPossum prays for his complete and quick recovery.
