Sergei Millian—a Belarus-born businessman who served as an unwitting source for the infamous Steele dossier—built a working relationship with Trump aide George Papadopoulos in 2016 and offered to serve as a go-between for the Trump campaign and a Belarusan author with connections to the Russian government, The Washington Post reports. Millian has disappeared from public view since he was revealed to be one of Christopher Steele’s sources and has rejected or ignored attempts from House and Senate intelligence committees to interview him. The new report suggests he was closer to Trump’s world than was previously known. Papadopoulos thinks Millian was working with the FBI to target the Trump campaign—a claim rejected by the Post’s FBI sources. In an interview in 2016 with ABC News, Millian claimed to have high-level contacts in the Russian government and to have met Michael Cohen and Trump himself. The Steele dossier cited Millian as a source for the assertion that a “well-developed conspiracy of cooperation” existed between the Trump campaign and Russian leaders, he was also cited as the source for the “pee tape” allegations.
