Hate to say it but I think Obama has had dirt on all them for a while, which is why they shut up and do nothing the last 6 years we Tea Party folks sent them there.
BUT, by executive order, Trump can rescind Obama’s EO to seal his records.
That’s the big baby I am waiting for.
Someone like Obama would have precious few federal records that the feds could ‘unseal’. I would imagine Hawaii, Occidental College, Columbia, etc, have long since destroyed their Obama records to the best of their ability. A US president would have no authority over them in any case.
