Fox is saying scar tissue that caused the collapse of the lower lung. Weird. They keep saying it's not life threatening but any surgery is risky.
I don't see this guy outliving Bush 41, Carter, or mabye even Ford perhaps, who is past octugenarian I believe.
I hope he fully repents for his sins, lies, assaults and corruptions, for his own eternal sake, and wish him the best on his journey that we all have to make some day.
