Personal is defined as unrelated to the president’s official duties, like Clinton’s socks drawer tapes that were used to write a book about him. Had nothing to do with his official duties. Any record that relates to the president’s official duties, including all records generated by executive branch agencies, belong to NARA, the people’s custodian of records. The president is allowed to determine which records he believes are personal, but if any are later determined not to be he must return them. You’ve either been grievously lied to, or don’t understand the plain language of the PRA, or understand it but pretend it says something it does not because you can’t handle the truth about what Trump did.
