listen to what Trump's former Communications staff member, Stephanie Grisham, has to say...especially toward the end of this short video...she clarifies, in simple terms, why DJT can't just wave his hand over Classified documents and declare them "De-Classified" without going through a process for each of them that informs the agencies responsible for their content, to see if they agree, and if they do, give them sufficient time to 'move and/or deal with' the Sources and Methods that could very well be covered in those documents...to the best of my knowledge, this has not happened.
IMO, DJT is totally boxed in on this...thanks to his own big mouth, and inability to think and reason...be that as it may, keep Ms. Grisham's words in your mind as this all plays out. I fully expect her to be 'attacked' by several posters here, but there are attorneys with direct experience in defending and prosecuting Confidential document cases who say the exact same thing...she just simplifies it for you.
