The Blaze has covered several instances of anti-Semitism emanating from the Occupy Wall St. movement (despite the organizers’ attempts to trivialize it). And now, the group over at Whyoccupy.com has posted a powerful new web ad from the Emergency Committee for Israel, wondering why, despite the anti-Semitism, so many liberal politicians have come out in support of the movement.

“Why are our leaders turning a blind eye to anti-Semitic, anti-Israel attacks?” it asks: You can read about the anti-Semitism at the protests here, here, here, and here.
