This ProPublica article is good reading. It discusses a company used by many insurers, including UHC, to deny claims using AI. The name of the company is EviCore. I suppose the “Evi” is supposed to be short for “evidence” but I think it is pretty clear that it’s just short for “evil.”
Where did you get that idea? It’s been done before. In 1977 for example, President Carter, issued a blanket pardon to everyone who dodged the draft during the Vietnam war.
There are, in fact, very few limitations on the power of the pardon.
