Sobre llovido, mojado

[aleCcowaN]

I was watching a call-in show in The Line, one of my favourite channels, and the hosts were lamenting Trump's win. Not to become too political, they were reviewing their strategies supporting Harris and half joking about "the resistance starts today" and I thought "sobre llovido, mojado" that we use when you try to fix a problem, you may have contributed to or not, by talking actions that may make it worst.

I want to learn similar expressions in English and Spanish. It's not "adding fuel to the fire" because with "sobre llovido, mojado" either you are somewhat to blame for the original "fire" or neither the original fire nor adding fuel to it have depended on you at all.

Adding fuel to the fire/echar leña al fuego imply that inadvertently, maliciously or anything in between, you have done that but aren't liable for the original fire.
