The Mueller Report:
Manafort also twice met Kilimnik in the United States during the campaign period and conveyed campaign information. The second meeting took place on August 2, 2016, in New York City. Kilimnik requested the meeting to deliver in person a message from former Ukrainian President Viktor Yanukovych, who was then living in Russia. The message was about a peace plan for Ukraine that Manafort has since acknowledged was a “backdoor” means for Russia to control eastern Ukraine. Several months later, after the presidential election, Kilimnik wrote an email to Manafort expressing that view—which Manafort later said he shared—that the plan’s success would require U.S. support to succeed: “all that is required to start the process is a very minor ‘wink’ (or slight push) from [Donald Trump].” The email also stated that if Manafort were designated as the U.S. representative and started the process, Yanukovych would ensure his reception in Russia “at the very top level.”
Manafort communicated with Kilimnik about peace plans for Ukraine on at least four occasions after their first discussion of the topic on August 2: December 2016 (the Kilimnik email described above); January 2017; February 2017; and again in the spring of 2018. The Office reviewed numerous Manafort email and text communications, and asked President Trump about the plan in written questions. The investigation did not uncover evidence of Manafort’s passing along information about Ukrainian peace plans to the candidate or anyone else in the Campaign or the Administration. The Office was not, however, able to gain access to all of Manafort’s electronic communications (in some instances, messages were sent using encryption applications). And while Manafort denied that he spoke to members of the Trump Campaign or the new Administration about the peace plan, he lied to the Office and the grand jury about the peace plan and his meetings with Kilimnik, and his unreliability on this subject was among the reasons that the district judge found that he breached his cooperation agreement.
