America’s most influential pro-Israel lobby group, AIPAC is hosting its annual policy conference in Washington next week. All the presidential candidates were invited and all will be attending, except for one: Democratic presidential candidate, Sen. Bernie Sanders, who also happens to be the only Jewish candidate ever to win a presidential primary. Mr Sanders said he would be unable to attend because of his campaign schedule. “I would very much have enjoyed speaking at the AIPAC conference,” Sanders said in a letter released to AIPAC’s President Robert Cohen on Friday.
