Three biggest differences between Biden and Trump classified documents.

1) No criminal intent
2) No obstruction
3) No attempt to keep claim they're his

@TeaPain Tea, I've been looking at this from a slightly different angle (and getting very little traction). It appears that the White House has a problem keeping track of Classified Documents. It probably makes sense to take a good faith look at Pence's and Obama's paperwork as well as that of previous administrations just to be safe.
The point I want to make is this. If there was a systemic problem, and Trump recognized a weakness, *of course* he would find a way to exploit it rather than trying to fix it. It's his nature; he's like a hyena, always sniffing for any weakness that he can grift.
