If Trump did actually ever plan to release it all (not just “declassify”), he shouldn’t make a big production and build up a tick-tock-teaser out of it. Just dump it all out on tables for whatever interested media to pick up at the same time as it’s announced.
It is too late. He couldn’t get rebel agencies to release classified documents before; they certainly won’t comply now. We will see full on defiance by agencies that are Deep State controlled.
