The list of various types of person ([7] Congressional members + [3] Senators + [2] former O-senior officials + [4] OUTSIDE CONTRACTORS) is a list of people observed to have enetered a specific SCIF. Some of the pole allowed to enter lack the security clearance associated with that particular SCIF. Who allowed them to enter?
I think this action, entry by unauthorized persons, is common based on perceived rank, e.g., being a Senator. But for this entry, there is also a question of future leaks to/in the press, likely in the next day or two.
They are there to see the Shifty Memo, not the Nunes Memo. Its to get all the talking points out tomorrow before the SOTU. Before Trump officially releases the Nunes Memo Shifty can get his memo out by leaking.
Are these the people named in the memo Therefore they are in the skift?
Take them to Gitmo and make them talk.
