Trump says they have given them everything they've asked for when they've asked for it. If not true shouldn't they tell us what/when they asked for something and what Trump wouldn't turn over? If Trump was lying it seems like they'd say so.
That is a wilfully deceptive claim, which is why the fact that an informant notified the DOJ is so critical. When the DOJ investigators, headed by Bratt went to MAL on June 3, they had a Grand Jury subpoena for specified documents THAT THEY WERE AWARE OF.
Since the boxes the FBI retrieved on Mon included material that was delegated TS/SCI that means that while the Investigators were there on June 3, the folks at MAL did NOT even bring up the additional documents which they knew they had but weren't specifically listed in the subpoena. They purposely omitted any discussion of those documents, even though they had been warned by the NARA since May of 2021, that they needed to return ALL the classified documents on hand.
We don't know WHY they omitted mentioning/providing the documents they knew they were supposed to return. But the fact that they had done so was made abundantly clear to DOJ when an informant (possibly Jared) reached out to DOJ and informed them there were additional documents at MAL beyond what Trump "willingly" returned.
The person knew of the existence and location of the safe, which means it was someone from Trump's inner circle. So everyone within the inner circle (7 or 8 people) would have to be privy to the same info as the informant. So all of them, including Trump were basically complicit in NOT advising DOJ that they had additional TS/SCI designated material, beyond what was listed on the subpoena .
Even if they mistakenly thought Trump had declassified them (which would have necessitated him making that known to EVERYONE in Congress with that clearance) they should at the very least have disclosed they had them so any security issues could have been dealt with properly.
These type of documents can only be viewed in a secured location, like a location within the Capitol where an armed guard is stationed and all communication devices are left outside. They contain sensitive info beyond just a TS clearance, and could easily include names of US operatives abroad. I have read that the FBI is even considering dusting them for fingerprints to determine if anyone who does not have that level of clearance has handled them. They definitely should NOT have been anywhere near MAL...
