In April 2014, for instance, Manafort traveled to Vienna. Ukrainian oligarch Firtash had been arrested there the prior month on U.S. charges that he helped orchestrate an $18.5 million bribery scheme involving the government of India, a U.S. firm and a Firtash company in the Virgin Islands. A former U.S. government official, who declined to be identified because of the sensitivity of the matter, said Manafort met with Firtash in Vienna, where he is awaiting extradition to the United States.
Another Manafort trip that could interest investigators took place in July 2013 when Manafort and his associate Kilimnik flew to Frankfurt on a private plane owned by Andrey Artemenko, a pro-Moscow Ukrainian legislator.
American experts on Russia said privately they suspect the trip was a prelude to a broader Russian influence effort to dissuade Yanukovych’s government from signing an agreement to associate with the European Union. That decision, experts say, opened the door to Russia’s 2014 invasion of eastern Ukraine. This year, Artemenko was expelled from the Ukrainian legislature and his citizenship was revoked after disclosures he and a Trump attorney had pitched a “peace plan” for Ukraine and Russia widely seen as favoring Moscow.
