The security briefing afforded the presidential candidates prior to a presidential is a general situational awareness briefing, likely a sanitized version of the PDB, and it’s prepared for the candidate by the government as a courtesy.
I would not be surprised is the current administration decides that it’s “too dangerous” to let Trump have access to any classified information and either snubs him directly (which is politically risky), sanitizes the heck out of anything they provide so it’s not useful in any meaningful way for situational awareness, or tries to plant items in the briefing (that may not even be accurate or even accurately classified, but will have classification markings) that they know Trump will blurt out in campaign appearances so they can frame him as reckless with classified information one more time.
Knowing how dirty a dirtbag like Barry has long dealt and played his hand, one would have to check PDJT’s previous (pro-PDJT) briefers (which do exist), to see whether any have met with unfortunate events, e.g,. accidents, litigation, health issues.
I’m sure those few brave souls have not come through Biden’s term unscathed. It’s all tantamount and parallel to the arrests, attempted fraudulent jailing, financial ruin, election interference and attempts at assassination that PDJT has had to face.
