CNN: FBI Used Debunked Trump Dossier To Get FISA Warrant for Surveillance
‘Comey and other FBI officials would have had to sign off on this’

PEREZ: “Well, Anderson, U.S. officials tell CNN that last year the F.B.I. used a dossier of allegations of Russian ties to Donald Trump's campaign as part of a justification to get approval to secretly monitor Trump associate Carter Page. FBI Director James Comey has cited the dossier in some of the briefings to members of Congress in recent weeks as one of the sources of information that the bureau has used to defend or to support its investigation. This includes approval from the secret court that oversees the foreign intelligence surveillance act known as FISA, to monitor Page’s communications. To obtain court permission to target Page, the FBI and the Justice Department would have had to present probable cause that he was acting as an agent of a foreign power, including possibly engaging in a clandestine intelligence gathering for a foreign government. Comey and other Justice Department officials would have had to sign off on this application. Last year Page was identified by the Trump campaign as an adviser on national security matters, though they have since said that he had limited interactions with the campaign as a volunteer.”
