Serious question: Are you brain-dead?
Nobody celebrates a felony conviction. The people you get your propaganda and conspiracy theories from are pissed about this verdict. They (and you) wanted an acquittal so they could argue the fix was in, continue with the bullshit two-tiered justice system argument, "weaponization" of the federal judiciary, etc. This verdict flies in the face of that nonsense.
New presidents regularly replace existing US Attorneys. Biden could have easily replaced the Trump-appointed US Attorney in Delaware (Weiss) when he became president. Instead, and with the Hunter investigation already underway, he left Weiss in place to avoid any suggestion of interference. Today, as Special Counsel, Weiss secured the conviction he was after.
Joe Biden commented, after the verdict, that he "will accept the outcome of this case and will continue to respect the judicial process as Hunter considers an appeal." Compare and contrast that with the Chaos Candidate's comments after he was convicted. "Rigged," "disgrace," "corrupt," "fascist state," etc. His son called the US the equivalent of a "third-world shithole." They should both get the fvck out.
