Is Hunter Biden president? Does he hold any public office at all? There's your difference. Trump is currently under investigation for potentially selling information on other nations' nuclear capabilities to the highest bidder. That's a lot more damning than some yuppie's supposed crack addiction. Especially given that everybody in the highest income brackets has done cocaine at some point.
So he shouldn't be investigated for illegal doings linked to his father? I guess it is (D)ifferent for you.hunter didn't even hold any office position to my knowledge. Unlike Trump's kids.
I really don't understand how you don't find the possibility of a compromised President not an issue. Anyone getting security clearance is checked along with their immediate family to make sure they can't get black mailed. But I guess that doesn't matter for you.
