Earlier quoted context omitted.
Probably (not a legal scholar) but I'm sure it applies to sitting presidents, not former presidents.
But wasn't he President when he took the documents to MAL, or at the very least, when he packed them to go to MAL? Or did he somehow take them after leaving the White House? I don't know what charges the FBI will bring in this case, but for the sake of the nation, I hope they are something more serious than just failing to write a note saying "I authorize myself to take these documents."
It honestly does not matter at this point. Remember when Trump said “I could stand in the middle of 5th Avenue and shoot somebody and I wouldn’t lose voters"? Still holds up today and he's not even running for anything. The feds can find the most damning evidence of the most heinous crimes and will still not change the minds of the MAGA crowd. We're in the post-reason context right now.
