[Paul Manafort] grew reliant on Konstantin Kilimnik, a Soviet-born native who could render idiomatic English and translate the cultural nuances of the region that might elude outsiders. Manafort would describe him to others in his office as “my Russian brain.” For a decade, Kilimnik was a fixture in Manafort’s meetings with the region’s leading politicians and oligarchs.
After so much time spent in close quarters, the relationship between the two became trusting and deep. By 2011, Kilimnik had taken over Manafort’s office in Kiev. This made Kilimnik the primary interface for Manafort’s lone client, a corrupt clique of former gangsters that ruled Ukraine under the banner of their political organization, the Party of Regions.
With his access and his ability to trade information, he built an impressive network. His rolodex came to include reporters from big international news organizations, including The New York Times, as well as denizens of Washington think tanks and diplomats. They would describe him as “user-friendly”—unusually smart, almost always available, and able to perfectly express complex thoughts in English.
The office of Special Counsel Robert Mueller recently confirmed that Kilimnik is the focus on a grand jury investigation.
