Nate Jones, author and director of the FOIA Project of the non-profit National Security Archive, has a succinct answer:
I don’t. In this respect I think Trump will act like the presidents before him and have his opinions dictated by the disingenuous but hair-on-fire memorandums from the intelligence agencies warning of “grave irreparable harm” to US espionage capabilities if all the information about what US spies were doing nearly 55 years ago during the JFK Assassination is released.
It’s a pity the US National Archives did not simply release the information last October when it had the tacit green light. Now, I predict the intelligence community will instruct to the president to sign off on the continued withholding of a substantial amount of material, and the president will listen to their orders.
