On January 12th, 2017 Inspector General (IG) Michael Horowitz announced his investigation and identified the initial scope of his investigation.
The Impetus – “in response to requests from numerous Chairmen and Ranking Members of Congressional oversight committees, various organizations, and members of the public”
The primary sources are the oversight committees and we are going to focus on them due to the public availability of documentation. Keep in mind that “various organizations” INDICATES organizations such as Judicial Watch, the ACLJ, and other organizations whose IG requests have not been made public. Also keep in mind that “members of the public” are the ever important and confidential whistle blowers. What we are going to do in this thread is match up source documents from the oversight committees to the IG Report. I will demonstrate that they are the main thrust of the investigation, and that the expanse of the investigation has expanded since the initial announcement. What we will not be able to do is identify what the IG is investigating due to “other organizations” and “members of the public”. We are going to explore “other issues that have arisen” that we have evidence of.
The Disclaimer – Placing Responsibility on the DoJ There are two parts to the IG disclaimer. The first part he lets the public know that he cannot open/re-open investigations or prosecute.
In Horowitz War vs. The Obama Admin he allied himself with Congress. This is the continuation of that war. This is the mop up operation and he is once again working with Congress towards that end. That end is reached by a special counsel and there are two paths to get there.
Both paths go through the DoJ. They can appoint one on their own or be forced to by Congress. The evidence will simply be too overwhelming to do otherwise. It will look like the IG and Congress vs. the DoJ but make no mistake about it the DoJ/FBI good guys are in on it. The Initial Scope Bullet Points Comey, Kadzik, FOIA, and the Hillary Clinton email investigation. (Note: Nothing STATED about the Steele Dossier and the plot against Trump)
October 11th, 2016 House Judiciary Committee letter asks the IG to investigate the circumstances of Hillary Clinton’s interview which opens the door to the politicization of the FBI Comey and PeterStrzok 
November 2nd, 2016 Senate Judiciary Committee fires off an electronic letter focusing the IG on
McCabe, Kadzik, and Lynch (Tarmac) 
November 2nd, 2016 Miami Florida – Trump discusses Kadzik and Podesta – C-SPAN
Kadzik and Podesta , 
Kadzik was the DoJ Assistant Attorney General for Legislative Affairs. He resigned and was replaced by Trump nominee Stephen E. Boyd 
Now we get to the good stuff. Mr. Boyd notifies the House Judiciary Committee that he forwarded two letters to Michael Horowitz to determine if he should expand the scope of his investigation. 
It Begins July 27th, 2017 House Judiciary Committee Calls for a Special Counsel on legal grounds pursuant to 28 CFR 600.1
14 Questions for the IG! This powerful letter is a thing of beauty that expands the scope and establishes the legal framework for a special counsel. Read in it’s entirety to see where we are headed. (Steel Dossier, Uranium One, Clinton Foundation) 
It is clear that Congress and the DoJ/FBI are getting out in front of the IG Report. Keep an eye on events and how they directly correlate to the initial IG statement and the 14 Questions for the IG in the 7/27/17 letter.
14 Questions Summary
1-5 Clinton email investigation
6-8 Clinton Foundation Uranium One
9 DNC Election Rigging
10 -14 Weaponized DoJ/FBI Steele Dossier – Russian HOAX
Comey’s Lies are catching up to him. September 26th, 2017 continues the call for a special counsel as well as targets Comey’s lie to Congress. They have Comey dead to rights.
James Comey says he closed the Hillary Clinton email investigation AFTER he interviewed her despite crafting a letter of exoneration prior to doing so. – C-SPAN
The July 27th letter is the key document. Everything needed to appoint a special counsel is contained within it. The letters preceding it were precursors and the ones after are add ons. All the IG has to do is reinforce that letter and a special counsel will be appointed. The House Judiciary Committee will not let up on the call for a special counsel. Jordan wants one now. Rosenstein cannot commit until after the IG investigation is complete. – C-SPAN
The HJC established legal standing for a special counsel but needs the evidence from the IG to seal the deal for a SC. The DoJ needs the IG Report in order to IMPARTIALLY appoint a SC. They both need the same thing.
This report will be the highlight of Horowitz career as well as that of everyone in his organization. It will be the most significant report to ever come out of the Inspectors General. He will give the HJC and the DoJ what they need to appoint a SC. It is inevitable.
What was Michael Horowitz doing prior to January 2017? From 2011-2016 he was engaged in a protracted war with the Holder DoJ and Obama Admin. A war he finally won in November 2016.,

Focus primarily on these Congressional Committees and their Chairmen as they are the ones driving the action: House Judiciary Committee: Bob Goodlatte Senate Judiciary Committee: Chuck Grassley House Select Committee on Intelligence: Devin Nunes
Keep an eye on the DoJ/FBI and how they respond to the action. At times they will appear at odds with Congress, but make no mistake about it, they are working together and their actions will line up.
For those that are paranoid about the DoJ/FBI leadership and want to view them as an adversary that is fine. IT WILL MAKE NO DIFFERENCE. Even if they were opposed to cleaning up (which they are not) they are between a rock (IG) and a hard place (Congress) and will comply. Lastly, for amusement pay attention to the targets of the investigations and their surrogates in both the media and Congress. They will attack, distort, distract, and flail about in panic. Do not worry about them. They are powerless and along for the ride. ALL OF THEM.
