Yes. He can order the military (seal team 6 or something) to put a bullet in his face. That's a presidential action. Whoever does it though could be charged. The president could then pardon (another presidential action) everyone involved.
After Nixon resigned, he was pardoned before he was even charged so...
I grew up in Iowa and can confirm there are tons of hogs. It seemed like every farmer I talked to had like 3 if not more hog confinements.
The smell is always worst when the farmer is pumping out the pit to fertilize the fields. I'm pretty glad I never got into farming.
