Some interesting thoughts about the secret document investigation.
It is clear to me Trump believed his resort, office, desk, were off limits to the DOJ/FBI. Big mistake. Trump knew he was being investigated for months, he was subpoenaed in May. Yet he left secret documents in his desk. This is exactly the type of mistake a textbook narcissist would make.
It is reasonable to assume Trump must have hand picked what secret documents to return and what secret documents to continue to hide. After all they were HIS documents. Why did he hide certain secret documents and return others? Might be some clues there.
When the FBI seized documents they take all the documents in that area. When they found secret documents in Trumps desk they must have taken all documents in his desk. What else was in that desk. Could there be messages, letters, hand written notes about things that are corrupt. Could there be evidence about the Jan 6th investigation in that desk. It's possible, after all Trump thought his desk was off limits.
Listening to prosecutors on TV it is becoming clear to me The DOJ has a smoking case for obstruction. That is a serious felony. This charge can be prosecuted separately from other charges. According to prosecutors, in an obstruction case The DOJ would not have to worry about showing the secret documents, it is not necessary in an obstruction case. They just have to prove Trump obstructed their investigation.
Other charges could be brought later.
