One of America's worst governors strikes again.
I don't live in NJ, but I do have some close family members there.
If they want or need plastic bags, I expect they will simply drive into Pennsylvania or New York or do their shopping there.
In the meantime, NJ residents: if you find yourself searching in vain for reusable room trash can liners or pet waste collectors (as everyone but Phil Murphy seems to know are what people use plastic shopping bags for), I would suggest you stuff your unwanted waste in a Democrat politician's mouth.
