Because it's not worth the resources to worry about. The GOP is just doing it because they don't actually know how to govern; they need something they can point to that looks like they're actually doing something, and they know it spins up their low education voters.
Pretty much this. The democrats put their resources into passing infrastructure and inflation bills and investigating the events around Jan 6.
Everyone agrees that the Trump kids got up to no good but the relative seriousness of their crimes compared to everything else Trump did was pretty small.
Since the Republicans have no actual dirt on Joe Biden and are about as capable of passing legislation as a bag of ornery chipmunks, they latch onto these 'scandals' that would barely be a blip for any Republican administration.
Nepotism isn't actually illegal (though it'd be nice if it were)
You can't prosecute someone based on laws you feel should exist. That's what fascists do.
If you have issues with this sort of thing (which happens at all levels of politics and business, not just with Trump and Biden), then you should write your representative about it and advocate for new laws to be made.
Hell, id cosign that letter, but I wouldn't advocate for the prosecution of someone based on laws that don't exist, not even the Trumps (though I do happily advocate the many prosecutions underway for the things they've done that are genuinely illegal)
That circular reasoning. Investigations are conducted based on evidence. If there’s no evidence of illegality, then there’s no reason to investigate. You can’t just go violating somebody’s rights because you suspect something. That’s why cops have to get warrants.
You have evidence. An investigation is to provide further evidence.
You do not investigate something you have no evidence of, otherwise I'm just going to call the cops and tell them you fuck goats. You're a goatfucker and they need to investigate you as a goatfucker, because you fuck goats. I know you do, so you are a goatfucker.
Do you understand even the most vague aspects of the judicial system or do you get all of your information from CSI?
