There seems to be lot of things going behind the scenes. The very fact that the MSM was not aware of the raid and even filed supporting applications to release the affidavit clearly shows that they are unware of what is going on which means that white hats are in control and DJT is not the subject matter of investigation.
Now, if you read Point#2 of the redacted affidavit carefully with the assumption that DJT is not the subject matter of investigation, it would appear that the investigation is being carried out to find person(s) who have intentionally and without involvement of DJT sent classified information documents from WH to Mar-a-Lago, either to frame DJT or to remove those documents which were required and were part of some other investigation!!
