The previous president was found to have taken a large stash of some of the most extremely sensitive documents in the US classification system - the kind where they are only allowed to be viewed in specially constructed rooms. The government asked for them back. He refused and attempted to retain the documents. They were eventually forced to get a warrant to forcibly retrieve them from his property, and he may face charges for it.

The current president's lawyers discovered some classified documents (uncertain what level of classification) obtained during his time as vice-president from 2009-2016 while going through some things in an office they were shutting down. They alerted the proper agencies and a thorough search is being performed to make certain that there weren't any more.

Some people want to equivalate the two incidents to paint a narrative. However, the real legal difference is that one man attempted to stonewall authorities, hide, and keep TS/SCI documents while the other is proactively cooperating to make sure that any others are found and returned.

Possession of said documents isn't necessarily a criminal act, but attempting to retain them and lying to the FBI may be.

One top secret, rest secret or lower.  Highest classification is top secret SCI, ie compartmentalized info that only people “in the know/on a need to know basis” are told, like some of those found at trumps.

There’s a blackout on info from the whitehouse because they’re observing the law &amp; not trying to obstruct council.
