Essentially the FBI wanted Steele to somehow miraculous come up with corroborating material for what Steele knew was a pack of lies. From Natalia Mittelstadt at justthenews.com:
Following the bombshell revelation from the trial of Igor Danchenko that the FBI offered Christopher Steele $1 million to corroborate his dossier, former House Intelligence Committee investigator Kash Patel said this proves the bureau knew it hadn’t been able to verify the Trump-Russia collusion narrative and misled Congress.
As the prosecution opened its case against Danchenko Tuesday, Special Counsel John Durham questioned his first witness, FBI supervisory intelligence analyst Brian Auten.
Auten testified that in early October 2016, the FBI offered Steele “up to $1 million” to provide corroborating evidence for his dossier, but the former British spy didn’t provide any such information to the bureau. As a result, Steele wasn’t given the money because he was unable to “prove the allegations.”
An application the FBI submitted to a FISA court on Oct. 21, 2016 for a warrant to initiate electronic surveillance of former Trump campaign adviser Carter Page included uncorroborated information from the dossier. Auten testified that before the FBI received the dossier, it didn’t have enough evidence to obtain a FISA warrant.
