The central claim of the memo is that the FISA surveillance applications relied on a controversial dossier by former British spy Christopher Steele, whose raw intelligence reports claimed that Trump campaign officials had met with Russians and that Russian intelligence had information sufficient to blackmail Donald Trump. Steele was a Russia expert for MI6 and had provided credible information to the FBI in the past.
The Nunes memo does not say Steele’s dossier was the only piece of information used to establish probable cause that Page was acting as a foreign agent. Indeed, when FBI agents submit a FISA application to the Foreign Intelligence Surveillance Court, they use information from multiple sources, according to current and former FBI officials. What’s more, the same information is not used over and over to extend surveillance under FISA. Instead, every 90 days, the FBI, as a matter of practice, shows evidence to the court that agents are obtaining foreign intelligence information through the surveillance that is in line with the initial FISA application.
According to the Nunes memo, the FBI received three 90-day extensions to monitor Page’s communications under FISA authority. This would have required the FBI to show Justice Department lawyers and the FISA court judge that Page’s intercepted communications included relevant foreign intelligence information. In fact, according to the memo, two Trump appointees at the Justice Department — Deputy Attorney General Rod Rosenstein and Dana Boente, who served as acting attorney general after Trump fired Sally Yates — reviewed this information and signed off on submissions to the FISA court.
What’s more, it’s highly doubtful that the FISA court judge would not have known about Steele by the time Page’s surveillance came up for renewal, as the Nunes memo suggests. BuzzFeed published Steele’s dossier in full in January 2017.
“Steele was out there. He was in the press at this time,” said Faiza Patel, co-director of the Brennan Center’s Liberty and National Security Program. “It’s ridiculous to believe that the judge had no idea who Steele was as this is being renewed over and over again.”
According to reports from journalists, unnamed Democrats on the committee have already begun to dispute the memo’s claim that the Steele dossier was an “essential part” of the evidentiary basis for the warrant applications.
