3 or 4 versions of dossier

Strzok wrote in the email, “our internal system is blocking the site. I have the PDF via iPhone but it’s 25.6MB. Comparing now. The set is only identical to what McCain had. (it has differences from what was given to us by Corn and Simpson.)” Strzok was referring to the BuzzFeed version of the dossier posted online, according to The Hill.  And the revelation is significant according to lawmakers that noted the FBI should be working diligently to ensure that there is no manipulation of evidence or stacked circular reporting in investigations.

Last week, SaraACarter.com revealed that Baker also met with the Democratic party’s top lawyer, Michael Sussmann, to discuss the ongoing investigation by the bureau into the Trump campaign’s alleged ties with Russia.

According to Baker’s deposition, the meeting happened prior to the FBI’s initial warrant to spy on short-term campaign volunteer Carter Page, sources close to the investigation have told SaraACarter.com. Moreover, information provided by Baker coincides with the House Intelligence Committee’s final Russia report that suggests Sussmann was also leaking unverified information on the Trump campaign to journalists around the same time he met with Baker, according to the report and sources close the investigation.

The information exposes the bureau’s failure to inform the secretive Foreign Intelligence Surveillance Court (FISC) that the evidence used to spy on Page was partisan and unverified, lawmakers told this news outlet. It further reveals the extensive role and close connection Sussmann, a cybersecurity and national security lawyer with Perkins Coie, had with the now-embattled research firm, Fusion GPS.

So if the above was for FISC/FISA optic of legality, Sally Yates cockblocking the IG from the NSD working papers would have been for the National Security Letters.

If you can't read it, it says:

We considered the Section 215 request for [REDACTED] discussed earlier in this report at pages 33 to 34 to be a noteworthy item. In this case, the FISA Court had twice declined to approve a Section 215 application based on First Amendment Concerns. However, the FBI subsequently issued NSLs for information [REDACTED] even though the statute authorizing the NSLs contained the same First Amendment restriction as Section 215 and the ECs authorizing the NSLs relied on the same facts contained in the Section 215 applicants…

In other words, the FBI had a neat way to get around a rare FISA Court rejection: just issue an NSL and ignore the First Amendment concerns.

Apparently, to some, whatever weak "oversight" there is from the FISA Court really just means "find another door in to violate the same Constitutional issues."
