In a conversation leaked online and posted to YouTube on Feb. 4, voices closely resembling those of U.S. Ambassador to Ukraine Geoffrey Pyatt and U.S. Assistant Secretary of State Victoria Nuland discuss loosely the roles of Ukrainian opposition leaders and the United Nations, and frustration over inaction and indecision by the European Union in solving Ukraine’s political crisis.

The woman, who sounds like Nuland, can be heard on the recording saying “fuck the EU,” while the man, who sounds like Pyatt, refers to Vitali Klitschko as the “top dog” among opposition leaders but implies that Klitschko is too inexperienced to hold a top government post.
