Ah - didn’t realize that - thanks for clarifying - makes sense now - the NSA Rogers sounded like a standup guy who was looking after the interests of the country, not the deep state.....
Well ironically you can’t get much deeper state than the Director of the NSA. But it seems that Admiral Rogers is a patriot and stand up guy. He caught wind of the scheme against Trump because as head of NSA he saw the massive increase in unmasking of transcripts that Susan Rice was authorizing on behalf of the Obama White House. She was basically unmasking everything she could get her hands on hoping to find the name Trump or a Trump associate on the USA end of the call.
He followed the lead and discovered it led to the fraud on the FISA court. When the FBI caught wind that Rogers was going to submit evidence to the court they did an end-run and modified their warrant request to include a small reference that the dossier was funded by a political campaign. (Of course they did not refer to Clinton, or even “Candidate #1” the way they referred to Trump as Candidate #2. Had they told the court explicitly that the dossier was paid for by the opposition campaign the court may have taken a more dim view on allowing the warrant, though that is speculation. The court has basically acted as a rubber stamp for whatever the FBI asked.
Once Trump won the election, Rogers went to Trump tower to inform him of the conspiracy. As has been the case all along the media immediately mocked Trump but he was right.
