Hunter Biden and the Biden family were investigated for years by Congress. They came up with tax and gun form charges. Why would that stop Dems from prosecuting all the corruption and treason happening under this administration?
I'm not following the reasoning in your comment. So because fishing expeditions are possible we shouldn't ever go after political opponents for actual crimes?
And do you not see how those sort of investigations failing to turn up anything is precisely what makes people think the entire system is brokenly corrupt? You can't in good faith argue you think he was in that position on merit. He was (and is) a drug addict with no relevant skills, and he's making millions working on the board of directors for a Ukrainian gas company?
You can, for instance, make your same argument about Dick Cheney and his relations with Halliburton which were equally obviously corrupt. Yet lo and behold, plenty of showy investigations, and the political establishment finds that the political establishment did nothing wrong, well at least nothing deserving of anything worse than a few very gentle taps on the wrist.
