Some speculate Barr already has Horowitz’s report, could be. Barr may be strategizing how to proceed, it is a complicated matter.
The underlined bit is what interests me.
Horowitz will report on compliance with the FISA procedure, how the warrants were premised, the sufficiency of probable cause, its substantiation, adequacy in the submission of exonerating evidence.
It has been reported the IG found the three renewed warrants were in fact non-compliant (due to an absence of further evidence from the original warrant and each of its successive renewals). In theory a 90 day warrant to monitor communications is supposed to reveal some evidence of criminality in order to be renewed, and no such evidence was ever produced.
This is very important because the DoJ’s investigation of all aspects of the Russia collusion hoax would necessarily interfere with the IG’s investigation of FISA compliance where the same participants were involved or there was reliance on information obtained via the FISA warrants.
The FBI is under the DoJ which stands down any investigations while the OIG is on the same matter. I expect the DoJ, DoS, FBI, CIA and NSA have been ‘easing out’ members of their upper echelons who were involved.
I’m more curious about what transpires from the IG’s report, if Horowitz already determined the three FISA warrant renewals lacked evidence of further criminal communications, and the first application didn’t adequately note exonerating evidence (like Page’s reported cooperation with the FBI unmasking Russian spies years ago) then all evidence derived from Page’s surveillance would be inadmissible in a legal proceeding. We don’t know what evidence Page’s monitored communications produced, but we do know he was on Trump’s ‘team’ and can reasonably expect he communicated with Manafort and Stone, perhaps Cohen (I doubt it). But if “one hop” Manafort or Stone communications were the basis for any investigation of them, evidence obtained thereby could be inadmissible as “fruit of that poisonous tree.” I expect everyone indicted by Mueller who has been convicted will appeal adducing inadmissible evidence from unwarranted surveillance.
