On Saturday, GOP candidate Donald Trump tweeted an image that has been widely condemned as anti-Semitic—an image of Hillary Clinton and a Star of David, with $100 bills in the background.

Trump’s team had mined the image from a racist and anti-Semitic message board, Mic reported. A watermark on the image lead to a Twitter account known for violent, racist memes. Trump deleted the tweet and has been trying to fend off criticism by saying it was not a Star of David in the image.

Social media users were not amused by Trump’s explanation.
