Sept. 18, 2017: A secret order authorized by the court that handles the Foreign Intelligence Surveillance Act (FISA) to wiretap former campaign chairman Paul Manafort began after he became the subject of an FBI investigation that began in 2014. It centered on work done by a group of Washington consulting firms for Ukraine's former ruling party. The surveillance was discontinued at some point last year for lack of evidence, but the FBI restarted surveillance after obtaining a new FISA warrant, which extended at least into early this year. The second warrant was part of the FBI's efforts to investigate ties between Trump campaign associates and suspected Russian operatives.
