During the 2016 presidential campaign, Trump campaign deputy chair Rick Gates was in touch with an associate of chair Paul Manafort's whom he knew had been a Russian military intelligence officer, NBC News reported.
The information comes from an FBI assessment filed in court late Tuesday by prosecutors with special counsel Robert Mueller, as part of a pre-sentencing report for another defendant who has pleaded guilty to lying about his contacts with Gates.
Gates has also pleaded guilty in the Russia probe, admitting conspiracy and making false statements, and is cooperating with Mueller's investigation.
