Progressive advocacy group MoveOn is calling on 2020 Democratic presidential candidates to skip this year’s American Israel Public Affairs Committee policy conference.

In a series of tweets on Wednesday, the group cited four reasons for Democrats not to attend, including the conference’s links to Israeli Prime Minister Benjamin Netanyahu, the millions of dollars AIPAC spent to defeat the Iran nuclear deal, its peddling of “anti-Muslim and anti-Arabic rhetoric,” and its refusal “to condemn the anti-Semitism of Republicans.”
