"Haaretz" reported that Ross's work as a Middle East aide in the Obama administration was burdened by tension with special envoy George Mitchell, to the point that Ross and Mitchell sometimes refused to speak to each other. This report indicated that the tension was caused, at least in part, by Ross's occasional efforts to conduct negotiations with Israeli government officials without notifying Mitchell. For example, in both September and November 2010, Ross was said to have tried to persuade Prime Minister Benjamin Netanyahu to freeze settlement construction during negotiations with the Palestinian National Authority, in exchange for unspecified private assurances and a major military arms transfer from the United States.
