The meme Donald Trump tweeted Saturday, calling Hillary Clinton crooked by an image of the Star of David, was previously published on a White Supremacist website, Mic News reported.

Trump’s meme was widely criticized as anti-Semitic. Trump later deleted it and replaced the Star of David with a circle.

Mic News traced the meme and found that it had been used on /pol/ — a website reportedly frequented by white supremacists, neo-Nazis and anti-Semites. The image has since been taken down, but an archived version is still available.

Trump’s former aide, Corey Lewandowski, defended Trump’s use of the image, calling the backlash of it “political correctness run amok.”
