The White House says that on Tuesday Hillary Clinton will wrap up her trip to Cambodia with the president and head to the Middle East, where she'll meet with Israeli, Palestinian, and Egyptian leaders and attempt to mediate a truce. Even if Hillary manages to achieve peace in the Middle East in her final weeks in office, John McCain will only complain that they didn't send the Clinton he suggested.
