I do not see why “revelation” requires a “smoking gun”, unless the communications involved at the very top were not electronic. If NSA has complete data, then what’s needed is for someone to run the right algorithm(s), perhaps with a little tweaking, target a data range, and a team sifts through what comes out.
I suppose, a problem might be, who authorizes this, as it is not a matter of terrorism, as terrorism is usually defined.
We also need to keep in mind the idea that there was likely no need for explicit directives to the effect of “Go spy on Trump and pass around any dirt you find”. Obama signed off on the information distribution, therefor it was obvious to underlings what to do.
As an aside, I note that killing off leaders of terrorist groups is not very effective. Liberalism seems to have many of he same characteristics.
I never said anything about a “Smoking guy”. I simply said they will not be able to keep a lid on this and I stand by that.
