The Mueller investigation is allegedly looking into Ted Malloch, a Trump campaign adviser, for his many appearances on the Russian-controlled news channel RT, The Guardian reports. Investigators have reportedly contacted Malloch, an American author and political consultant, about the appearances. Malloch disclosed that he was questioned about RT to the right-wing author Jerome Corsi, who is a target of the investigation. “They thought maybe he was coordinating with Russia—and RT is Russia,” Corsi told The Guardian. RT is the Kremlin’s main platform for propaganda in Russia and also has a close relationship with WikiLeaks founder Julian Assange, who is responsible for publishing emails stolen from top Democrats by Russian intelligence.
