It's a farce. If Trump wanted to, he could have every communication by every coup member from 2015 to this moment delivered tonight and sitting on the Resolute desk in the morning.
You are overstating NSAs capabilities to monitor worldwide communications a decade or more ago. Having the identity of two of the phones provided to Mifsud by us are indispensable to unlocking the cabals web of contacts. Dont forget that Brennan, Clapper, and Comey were orchestrating all of this thru the IC and Deep State. Durham and Barr are trying to penetrate the spy network and overcome ongoing resistance to revealing who did what.
Anyone who thinks that this attempted coup was being carried out by just a handful of bad actors at the top is delusional. At a very minimum, hundreds of people were involved with many of them still in place. They are obstructing the release of any evidence of their wrongdoing. Durham and Barr need to flip some people. The phone data from Mifsud could prove invaluable in that regard.
