As has been reported ad nauseum, nothing in the Steele dossier has been conclusively proven wholly false while much of it has been confirmed since it's release.
Directly from the IG exec summary on Crossfire Hurricane.
"8. Omitted the fact that Steele's Primary Sub-source, who the FBI found credible, had made statements in January 2017 raising significant questions about the reliability of allegations included in the FISA applications, including, for example, that he/she did not recall any discussion with Person 1 concerning Wikileaks and there was "nothing bad" about t he communications between the Kremlin and t he Trump team, and that he/she did not report to Steele in July 2016 that Page had met with Sechin;"
"Among the most serious of the 10 additional errors we found in the renewal applications was the FBI's failure to advise OJ or the court of the inconsistences, described in detail in Chapter Six, between Steele and his Primary Sub-source on t he reporting relied upon in the FISA applications. Although the Primary Sub-source's account of these communications, if true, was not consistent with and, in fact, contradicted the allegations of a "well-developed conspiracy" in Reports 95 and 102 attributed to Person 1 the FBI did not share this information with 01."
Page was not the entrance nor fulcrum that the FBI investigation was laid on.
It's obvious they really wanted Papadopoulos and/or Page. They couldn't get Papadopoulos, so there was no limit to the lying to make sure they got Page...and it was on the back of a report written by a notorious BSer, commissioned by democrats.
"The FISA request form drew almost entirely from Steele's reporting in describing the factual basis to establish probable cause to believe that Page was an agent of a foreign power, including the secret meeting between Carter Page and Divyekin alleged in Steele's Report 94 and the role of Page as an intermediary between Russia and the Trump campaign's then manager, Paul Manafort, in the "well-developed conspiracy" alleged in Steele's Report 95."
Elevating him as an example of errors doesn't eliminate all the other factual crimes and behaviors of Trump-related officials and Russians. Will you agree to that?
So abuse of FISA courts, lies and omissions should be standard operating procedure now? You're ok with all of this as long as the FBI gets their man? Where's the accountability?
I'll tell you what, a couple years from now when you find out Trump had embeds on Warren, Biden and Sanders, because the report has made clear he has plenty of supporters in the FBI, I don't want to hear a peep from the partisans about it.
