Re the SCIF: I guess some of the documents in question are classified or sensitive and can't be reviewed outside a SCIF.
And the defendant and his attorneys have an apparent need to review them as a part of the case (though I'm not sure I understand why -- the content of the documents isn't the point, but their status as classified and how they were taken/kept/treated by the defendant is)
Anyway, assuming he does have a valid legal need to look at classified docs for this case, why not park a mobile SCIF at Mar-A-Lago? That way it could drive away after the case is complete, rather than providing him free* remodeling services.
* I say free because even if he agrees to pay for it, we all know the chances of him paying that bill is near zero.
