This was the U.S. government conducting political opposition research through a weaponized intelligence apparatus (DOJ and FBI)

At The Conservative Treehouse, Sundance explains,

Unlike some, we will not get ahead of the primary focus. For over a year CTH has focused on the demonstrable and provable foundation of the fraud; because the foundation brings down the entire apparatus.

Following that investigative path we have found ourselves paralleling a strategic plan as outlined by actions of congressional officials (Nunes, Grassley, Goodlatte, Horowitz), and the Trump intelligence community [Mike Rogers (NSA), Dan Coats (ODNI), Chris Wray (FBI) and Rod Rosenstein (DOJ)].

Four Corners of the demonstrable justice dept. conspiracy:

Exonerate Clinton
Investigate/execute, IC surveillance of Trump.
Collect and redistribute opposition research of Trump.
The Insurance Policy.

Following the exoneration of Hillary Clinton, the next phase, the “Trump Operation”, was the need for the DOJ/FBI “small group” to have access to surveillance of Hillary Clinton’s political opposition, Donald Trump. This was the U.S. government conducting political opposition research through a weaponized intelligence apparatus (DOJ and FBI).

...Within the context of #2 and #3 you’ll note the entry and exit timeline of people connected to the same task is identical. Christopher Steele, hired by Fusion-GPS, enters the timeline at the same time Nellie Ohr is hired by Fusion-GPS (May 2016). Both Christopher Steele and Nellie Ohr exit the activity timeline at the same time as the FBI gets FISA Court “Title 1” surveillance authority over Carter Page, October 21st, 2016.

Everything after October 21st, 2016, when the FBI has “Title 1” surveillance authority over Carter Page and the Trump Campaign, is part of the “insurance policy”. The Title 1 surveillance authority gave the “small group” the tools needed to execute #4, which included the 2017 “Russian Narrative” and the appointment of SC Robert Mueller.

...Another example post-election use of the FISA surveillance was how the Intelligence Community positioned the story of Carter Page in April of 2017 to gain the Special Counsel appointment, ie. the Mueller investigation (another false construct.)

Expose the fraudulent construct of the “FISA Title I” surveillance and the tenuously sketchy narrative built upon it collapses. So, what is the weakest part of the FISA Title I construct? Answer: The Clinton-Steele dossier.

Expose the fraud behind the FISA “Title I” application and the entire scheme is revealed. Investigators expose the FISA application to disinfecting sunlight by going through the ‘Dossier’ it is built upon.

That’s why Chairman Devin Nunes, Chairman Chuck Grassley and Chairman Bob Goodlatte are focused on exposing the Dossier (Grassley), and FISA application (Nunes and Goodlatte); each complements the other.
