“Carter Page was, more likely than not, an agent of a foreign power. The Department of Justice thought so. A federal judge agreed.

“The Nunes memo alleges nothing that would even come close to meeting this standard,” he continued, referencing arguments that the warrant should be voided.

According to NBC, Nadler's rebuttal says the memo does not show the government lacked evidence to get a Foreign Intelligence Surveillance Act (FISA) warrant on Page and that former MI6 agent Christopher Steele, who compiled the dossier, had knowledge on Russia that would have trumped concerns a FISA court would have about the funding of the dossier.

Nunes's memo, which was made public on Friday, says the FBI's counterintelligence investigation into whether Trump campaign officials had improper contacts with Russia was triggered by information the bureau obtained about former Trump campaign adviser George Papadopoulos.

Allies of Trump had previously said it was the dossier that triggered the probe.

The memo alleges that the FBI used the dossier, in part, to obtain surveillance warrants for Page after the counterintelligence probe began.
