is not to actually investigate, but rather to give the outward illusion of investigation.
At one point in his political life Comey may have been a White Hat, but there’s no doubt his behavior is exactly what a black hat operative would be doing to shield his connection to the black hat activity of the prior administration.
Summary: Hillary Clinton political operatives manufactured the illusion of a computer connection between Russian entities (financial banks) and the Trump campaign/organization. Those manufactured points of evidence were then passed along to White House entities who used the political intel community (Clapper to Comey) to open an investigation of nothingness – to nowhere. The mere existence of that investigation was then used as the originating point for a series of media intel leaks (the narrative) intended to cloud and damage the Trump campaign/organization. FBI Director James Comey, as head of one of the investigative agencies, became part of that political apparatus. Now, usefulness exhausted and with the media engaged, it’s CYA time all around for the originating entities.
Sundance provides us with this video of freshman Congresswoman Elise Stefanik from New York asking FBI Director Comey what the protocol is on these investigations, and why the protocol was not followed (Comey did not brief senior Congressional officials until this month, even though the investigation began in July 2016, and the protocol required quarterly briefings of senior congressional officials).
“Because of the sensitivity of the matter” ~ James Comey's reply. It throws Stefanik off her line of questioning. She goes off in a different direction, and then comes back to it a few minutes later.
