Vermont Senator Bernie Sanders will skip the annual conference of the American Israel Public Affairs Committee, the powerful pro-Israel lobbying group. Sanders is the only candidate from either the Republican or Democratic Party not to attend the conference. His Democratic rival, Hillary Clinton, and Republicans Donald Trump, Ted Cruz and John Kasich are all slated to speak there. Sanders said his campaigning in Western states ahead of voting in Arizona, Idaho and Utah Tuesday would not allow him to make the trip to Washington, D.C. His campaign said AIPAC rejected his offer to address the conference by video link, even though Republicans Mitt Romney and Newt Gingrich did so in 2012.
