Trump has Rogers at the NSA....Rogers staged an unusual meeting with Trump where he did not inform his direct boss that he was going to Trump tower. I suspect this is how Trump found out about these taps. Expect Rogers to pop up soon in all of this.
Did you see this article regarding Admiral Rogers? VERY interesting. I was very unhappy to see the ‘other’ Mike Rogers, the former House intelligence Chairman (retired) associated with the Trump campaign. I was happy but mystified when he abruptly departed - this article might contain the answer & it well could be related to Admiral Rogers. Also, the timeline of when Admiral Rogers saw Trump in relation to what was going on in October (FISA warrant approved) is interesting. He upset some folks with that visit .... Clapper, Ash Carter.

A former Secret Service agent stated in a recent youtube video, SS agents always sweep an area for the person they are escorting for bugs. It is a very thorough evaluation for electromagnetic radiation of any sort. As Trump had SS coverage as a candidate, it would have been discovered.
