Israeli news agency Ynetnews reports that microphones accidentally left on after the G20 summit in France last week picked up a private conversation between U.S. president Barack Obama and French president Nicolas Sarkozy in which both men badmouthed Israeli Prime Minister Benjamin Netanyahu. Sarkozy told Obama that Netanyahu was a "liar" and that he "can't stand" him, and Obama responded: "You're fed up with him? I have to deal with him every day." According to a report, journalists present at the event were requested to sign an agreement to keep quiet about the comments, but the French website Arrêt sur images broke the story Tuesday. A Reuters reporter who was present at G20 confirmed the veracity of the remarks.
