No one said that. You made that up, silly.
The complaint here is that Biden is Trump's political opponent; the question is if the federal government can investigate Biden for actions he took as VP while he runs against Trump.
The answer is "Yes"
Why would or should it be otherwise?
Of course the federal government can investigate people who are running for office. But that's not the issue. The issue is whether an elected official should be allowed to specifically target political enemies for investigation. If you think they should, how will you react when a Democrat does the same thing? I realize that you will avoid answering that question until the cows come home, because the answer would expose your abject hypocrisy.
I'm game. Sure. Let's have all the politicians investigate each other. As long you only convict based on actual crimes, let's do it.
And here's the problem with your entire argument.... You say "how will you react when a Democrat does the same thing?"..... as if you people have not been doing this for a decade now.
Are you oblivious or something? Sparky... you guys have been propping up entirely politically motivated investigations for YEARS. YEARS you have been doing this.
I can think of dozens of politically motivated investigations over the past decade. You want a case an point? Bret Kavanough. Can't remember where the party was, when it was, who was there, or what specifically happened, didn't talk to anyone about it for decades, and the key collaborating witness says it never happened..... but that was grounds for demanding multiple investigations, even after the FBI said they did a full background check, and found nothing.
If you guys are not going to practice what you preach, then stop preaching it. It's that simple. You don't want politicians starting investigations for political gain... lead by example. Otherwise... save your breath for someone who cares.
