The report also indicates that the FBI terminated their relationship with Steele because he disclosed information to the media. But despite this termination, they used the information provided by Steele to obtain the FISA warrants.
The FBI, under the guidance of then-director James Comey, used more than one spy in its investigation into former Trump campaign adviser Carter Page, the government disclosed in a court filing on Friday.
“The FBI has protected information that would identify the identities of other confidential sources who provided information or intelligence to the FBI” as well as “information provided by those sources,” wrote David M. Hardy, the head of the FBI’s Record/Information Dissemination Section.
The filing by Hardy and the Department of Justice came in response to a Freedom of Information Act lawsuit to gain access to four of the FBI’s applications for Foreign Intelligence Surveillance Act (FISA) warrants against Page. While the applications were released June 20, they were heavily redacted, and "USA Today reporter Brad Heath has sued for full copies of the documents," The Daily Caller reports.
The filing says the "confidential sources" deployed by the FBI were in addition to Christopher Steele, a former British spy who reportedly authored a dossier on then-candidate Donald Trump. That dossier was used in order to obtain the FISA warrants, which give the FBI wide latitude in an investigation, including the power to wiretap.
