Wet suits on.
Of a lawfag.. but anons understanding is “how is evidence introduced legally?”
We have all the evidence via spy programs but the evidence has to make its way into public records for it to stick. This is where the chess board comes in… POTUS used the deep states own moves (Flynn, etc) to get evidence introduced that we already had… as one example.. out of many. Introduce evidence along the way to unlock moar and moar and moar.. the flood.
