Republican presidential aspirant Donald Trump is drawing flak yet again. This time, the problem isn’t the candidate’s comments about Mexico, but about a poor photo choice by his campaign.

On Tuesday, this photo was tweeted from his account – and later deleted:

Do you see those soldiers in the lower right side of the picture? They’re wearing Nazi uniforms. Trump’s campaign said an intern created and posted the image by mistake.

Mother Jones interviewed the British photographer who took the photo in question and found that it was a stock photo taken at a World War II reenactment. None of that was enough to stop the social media furor over the photo.
