There’s no way Trump just walked down the hall and picked up these files. If Trump said “gimme the info on Iran’s nuke program” then someone with a Very High Level Clearance with deep knowledge of what secrets we possess had to make up a very specific (file names, code words, etc) reading list and have Trump sign it. Someone with a VHLC then had to go to the appropriate SCIFs, request the documents, sign for them and deliver them to Trump at the WH.
Given the number of files discovered, there had to have been multiple lists and shopping trips. Does anyone really think that Trump requested these files out of a purely patriotic interest? Did he plan to sell them, or did he already have buyers?
The people with the VHLCs had to sign for these documents, and were no doubt videoed at every step of the process. Have they already been interviewed by the FBI?
