A salacious Clinton-campaign product was the driving force behind the Trump–Russia investigation.
On a sleepy summer Saturday, after months of stonewalling, the FBI dumped 412 pages of documents related to the Carter Page FISA surveillance warrants — the applications, the certifications, and the warrants themselves. Now that we can see it all in black and white — mostly black, as they are heavily redacted — it is crystal clear that the Steele dossier, an unverified Clinton-campaign product, was the driving force behind the Trump–Russia investigation.
Based on the dossier, the FBI told the FISA court it believed that Carter Page, who had been identified by the Trump campaign as an adviser, was coordinating with the Russian government in an espionage conspiracy to influence the 2016 election.
This sensational allegation came from Christopher Steele, the former British spy. The FISA court was not told that the Clinton campaign was behind Steele’s work. Nor did the FBI and Justice Department inform the court that Steele’s allegations had never been verified. To the contrary, each FISA application — the original one in October 2016, and the three renewals at 90-day intervals — is labeled “VERIFIED APPLICATION” (bold caps in original). And each one makes this breathtaking representation:
The FBI has reviewed this verified application for accuracy in accordance with its April 5, 2001 procedures, which include sending a copy of the draft to the appropriate field office(s).
In reality, the applications were never verified for accuracy.
