Yeah, Congress could always change the law, though I doubt the current one would. I’m just saying that there’s no current provision for revoking protection for a former president unless they were removed from office under Article II.

From what I can gather, the Former Presidents Act mandates lifetime protection for all former presidents unless they were removed from office under Article II. So the only current way for Trump to lose Secret Service protection would be for him to decline it.
