My guess would be that he would take documents home...and it depended where he was going that day.
And as of today...do we actually know that these are from when he was VP...or are they lying their butts off...and some of these are from when Trump was in office (likely) and even from his current "reign" as dictator.
What am I suggesting...The archives thought Trump had more files...and lo and behold...they're in Joe's possession. Just thinking...
I see 4 issues here.
1. Joe Biden probably had memory issues going on in 2016 already.
2. The National Achieves people who are supposed to ‘control’ this sort of thing (in packing) failed miserably.
3. The narrative being suggested that Biden’s ‘failure’ is nowhere near what Trump did...is screwed-up and juvenile in terms of logic.
4. Now, we discover that Hunter Biden was paying $49,000 a month for the home/garage....to Joe? It’s just all too convenient in timing. Scripted event for impeachment proceeding.
I’d bet that at least some magically appeared after he was installed and some were smuggled to him between 2016 and 2020.
