CNN has really been pushing this the past 48 hours.
"In a court filing earlier this week, the public saw the first signs of how the Mueller team plans to use information from Gates to tie Manafort, the former Trump campaign chairman, directly to a Russian intelligence agency. Mueller's team alleges that Gates was in contact with a close colleague of Manafort's who worked for a Russian intelligence agency -- and that Gates knew of the spy service ties in September and October 2016, while he worked on the Trump campaign. Gates would have to talk about the communication with the man if prosecutors wanted, according to his plea deal."
