No, it's not. Two recent examples are the Hildabeast and Joke Bribem. Both are as equally chargeable for mishandling classified documents as Trump, PERIOD! There's no if's, and's, or but's about that. They are equally culpable for that crime. That's just one example. In fact, throughout US history, certain parties, politicians, and people got away with the proverbial murder without so much as a how do you do, while others who pissed off the wrong parties got hammered.
If you need one example, I'd offer up J Edgar Hoover for starters.
We can go back elsewhere... the Hildabeast was banned for life from commodities trading back in the early 80's. The SEC declined to prosecute. During the Clinton administration there were numerous criminal scandals, the most egregious was likely "Chinagate" where China was paying bribes to get favors. Then there was the Clinton looting of the White House. The National Park Service declined to prosecute them after they returned most of the loot and paid a $92,000 penalty (civil fine for all intents) over the incident.
So, you are full of shit.
