One of the defenses he uses is that he could have easily declassified all those documents so there really is nothing wrong in the first place.
If that is not a lie and a President could have declassified all those documents, then why didn’t he?
He didn’t because without classification those documents would not have value. No country leader is going to pay for declassified documents.
There is a reason why highly classified documents were found in Mar-A-Logo and that is because they were going to be sold.
Trump most likely figured who would miss them anyway? Because any other president after him would not be aware of documents filed during his term of office. Therefore they were his and no one else could have them.
