Another point: The reality is that what Biden did, find some old documents and give them back, happens all the time and we need to build better systems to prevent that from happening. In the relevant law, intent is important and Biden apparently convinced the relevant people that he did not intend to keep these documents.

Trump meanwhile, clearly intended to take these documents, clearly lied to the feds about having these documents, gave some of them back when the feds said they knew he had them, lied about having more, and other stonewalling tactics. The feds TRIED to keep this hush hush for like a full year. If Trump would have given everything back at the first question, we might never have even heard of it.
