Maybe Trump can rescind Obama’s exec order that sealed all of his own records?
Which EO, by number, is that? Here is a link to help you out...
Barack Obama Executive Orders Disposition Tables
Or is this it? Executive Order 13489 Presidential Records
Presidential records aren't personal records.
Congress has a say on this too...
Public Law No: 113-187 (11/26/2014) Presidential and Federal Records Act Amendments of 2014
Anyway, if that's the EO you're talking about can you show me the words that "seal" his records?
Note - § 2201. Definitions
(2) The term "Presidential records"...
(3) The term "personal records"...
