"This was, the former spy remarks, "an extraordinary situation." He regularly consults with US government agencies on Russian matters, and near the start of July on his own initiativewithout the permission of the US company that hired himhe sent a report he had written for that firm to a contact at the FBI, according to the former intelligence officer and his American associates, who asked not to be identified. (He declines to identify the FBI contact.) The former spy says he concluded that the information he had collected on Trump was "sufficiently serious" to share with the FBI.
Mother Jones has reviewed that report and other memos this former spy wrote. The first memo, based on the former intelligence officer's conversations with Russian sources, noted, "Russian regime has been cultivating, supporting and assisting TRUMP for at least 5 years. Aim, endorsed by PUTIN, has been to encourage splits and divisions in western alliance." It maintained that Trump "and his inner circle have accepted a regular flow of intelligence from the Kremlin, including on his Democratic and other political rivals." It claimed that Russian intelligence had "compromised" Trump during his visits to Moscow and could "blackmail him." It also reported that Russian intelligence had compiled a dossier on Hillary Clinton based on "bugged conversations she had on various visits to Russia and intercepted phone calls."'
