According to a report in CNN, last year the FBI used a famous dossier of allegations of Russian ties to President Donald Trump's campaign as part of their justification to earn approval to covertly monitor Trump associate Carter Page. Page is the only reported individual in Trump's orbit during the campaign who had been subject to the Foreign Intelligence Surveillance Act (FISA). Officials familiar with the process told CNN that if the application to monitor Page had included information from the dossier, it would have only been after the FBI corroborated the information. It is unclear what or how much of the dossier was corroborated. The dossier alleges that Page met Russian officials as a representative of the Trump campaign, and discussed quid-pro-quo deals relating to sanctions, business opportunities and Russia's interference in the election. Page has denied these allegations.
