In September 2016, under the guise of discussing foreign policy, a woman who went by the name of Azra Turk asked Trump campaign adviser George Papadopoulos in a London pub whether the campaign was working with Russia, the New York Times reports.

The backdrop: Turk, masquerading as a Cambridge University research assistant, was in fact a government investigator sent by the FBI as part of a counterintelligence investigation into the Trump campaign's ties to Russia. According to the Mueller report, the inquiry was launched after Papadopoulos suggested to an Australian diplomat that the campaign had "received indications from the Russian government that it could assist the campaign through the anonymous release of information damaging to candidate Clinton."
