Biden is the worst politician in history, lol. How can someone so bad at politics be POTUS?
Trump's is actual espionage. Stealing and concealing classified documents, refusing to turn them over when asked (multiple times), and god knows what he planned to do with them or why he wanted them at all. Sell them to his buddy in North Korea? Give them to his daddy in Russia? No one knows.
Biden, on the other hand, is just a fucking idiot who can't get out of his own way. Nobody was looking for these, nobody even knew he had them. He found them, self-reported having them, turned them over immediately, and made a thorough search for more of them.
They're clearly different. Trump's is clearly malicious and Biden's is not. The end result is still gonna be Trump getting off scot-free for literal actual Espionage, though.
