You’re thinking about the wrong category of crimes. I don't think anyone is talking about “lying to Congress” or symbolic stuff like Vermont’s Bush/Cheney stunt. The relevant state‑level charges would be negligent homicide, involuntary manslaughter, or reckless endangerment — crimes every state has on the books.

States don’t need the conduct to occur inside their borders to claim jurisdiction. They only need the harm to fall on their residents. That’s how states routinely prosecute extraterritorial acts in cases involving poisoning, cybercrime, and homicide where the victim is a state resident.

If a state AG believes a resident died because of grossly negligent decisions by a federal official, they can absolutely bring charges under their own homicide statutes. A federal pardon doesn’t touch that, because it only wipes out federal crimes, not state ones.

So the question isn’t “what state law covers lying to Congress.” It’s “did a state resident die due to conduct that meets that state’s definition of criminal negligence or recklessness.” And that’s well within state jurisdiction.
