Though the GOP is trying to equate Biden's handling of documents with that of Trump, both Biden and Pence have actually cooperated with the national archives while Trump actively fights them, which is why the current president and former VP will likely face more leniency from the DOJ than their counterpart. As 2024 approaches, the potential presidential campaigns of Pence and Biden will face less controversy simply due to this fact.
As Biden continues to tout his cooperation with the national archives as evidence of his moral superiority, what the other side won't mention is that Trump's Mar-a-Lago was protected by the Secret Service, while Biden's documents were stashed in an unguarded public building. It's hard to imagine what the FBI would find if it raided the private property of any former president — say, Obama — because those politicians are friends of the powers that be, which is the true double standard here.
