Transcript for Top US Diplomat Caught on Tape Using Tough Vernacular On the Phone
Now, to a caught on tape moment for a U.S. Diplomat. What she said on a phone call I can't repeat here. It involved two of our diplomats talking on the phone about the situation in Ukraine. That country pulling away from the west. But it was in that phone call when asked about including our allies in Europe about the conversation, she uses a choice word. So, that would be great, I think, to help glue this thing and have the U.N. Help glue it. You know The E.U. I want to bring in Jonathan Karl, who happens to be with us in New York tonight, with reaction. First of all, not a word you would use typically to talk about an ally. This is a major embarrassment. This is the top U.S. Diplomat for Europe, insulting -- clearly insulting our european allies. As you can imagine, David, she immediately apologized. The obvious follow-up, this is between two U.S. Diplomats. Why are we hearing it at all? The white house implied it was the Russians who intercepted it and leaked it. And the circumstantial evidence is really strong. The world first heard about this on Twitter. It was a tweet from an official in the Russian government. To be specific, it was the assistant to the deputy prime minister. He put this out on Twitter. Tracking the tweets tonight. Who is spying on who. Jon Karl, thank you.
