A top State Department official has apologized to her European counterparts after she was caught cursing the European Union in a leaked audio recording that was posted to YouTube. The recording captured an intercepted phone conversation between the U.S. ambassador to Ukraine and Victoria Nuland, the top U.S. diplomat for Europe. Nuland expresses frustration over Europe’s response to the political crisis in Ukraine using frank terms.

Victoria Nuland: “So that would be great, I think, to help glue this thing and have the U.N. help glue it. And, you know, F—- the EU.”

Assistant Secretary of State for European Affairs Victoria Nuland is also caught on the tape showing just how involved the United States is in Ukrainian politics. She gives her blunt assessment of Ukranian opposition leader Vitali Klitschko.

Victoria Nuland: “I don’t think [Klitschko] should go into the government. I don’t think it’s necessary. I don’t think it’s a good idea.”

The leaked recording emerged while Victoria Nuland was in Ukraine, where she met with President Viktor Yanukovych and handed out food to opposition protesters. The Obama administration has suggested Russia is behind the leak. A Russian official, meanwhile, has accused the United States of “crudely interfering” in Ukraine. The spat comes as the Winter Olympics open today in the Russian city of Sochi.
