Starting as a driver for Davis, Ferry worked his way up and was assigned key responsibilities for some of the firm's foreign clients. They included a political party in Montenegro and a political leader in Ukraine, both backed by wealthy businessmen and oligarchs who sought to sway the outcome of elections in 2006 in those two nations...

In Ukraine, Ferry was part of a Davis Manafort team that advised Victor Yanukovich, the country's then-prime minister, whose pro-Russian party made gains in the 2006 parliamentary elections. (In 2004, Yanukovich lost to the U.S.-backed candidate, Victor Yushchenko, in a hotly contested presidential race.)

So Ferry was lobbying for the guy the American government opposed. And now he's one step away from a man running for president. National Journal gets the key quote from Larry Wilkerson, former top aide to one-time Secretary of State Colin Powell.

"When you take central advice from people who have advocated for foreign interests not necessarily congruent with American interests, it's really naive to assume that the advice you're receiving is not influenced by their previous work."
