A Hillary Clinton campaign aide slammed Donald Trump for tweeting an image that critics say featured a Star of David shape.

Hillary for America’s Director of Jewish Outreach Sarah Bard — who references reports that the now-deleted image criticizing Clinton as corrupt was previously posted on a message board associated with the white supremacist movement — condemned the presumptive Republican presidential nominee for his use of a “blatantly anti-Semitic” picture.

“Donald Trump’s use of a blatantly anti-Semitic image from racist websites to promote his campaign would be disturbing enough, but the fact that it’s a part of a pattern should give voters major cause for concern,” she wrote. “Now, not only won’t he apologize for it, he’s peddling lies and blaming others. Trump should be condemning hate, not offering more campaign behavior and rhetoric that engages extremists. The president should be someone who brings Americans together, not someone who sends signals and offers policies of division.”

The Trump campaign quickly took down the original tweet and replaced the image with one where the star was covered with a circle. Trump responded to backlash over the tweet Monday morning, blaming “dishonest media” for calling the six-pointed star a Star of David rather than a “Sheriff’s Star” or “plain star.”
