- The document outlines a timeline of events from 2015-2017 relating to opposition research conducted by Fusion GPS and others on the Trump presidential campaign. It indicates that in 2015 the Obama administration began surveillance of the Trump campaign and provided intelligence reports to the Clinton campaign. In 2016, Fusion GPS was hired to conduct research and hired Christopher Steele, who produced a dossier relying on Russian sources. The dossier and intelligence reports were then shared with the FBI and media and used to spread claims of Russian collusion and keep investigations of Trump ongoing after he became president.
