Republican presidential candidate Donald Trump on Tuesday night retweeted — and promptly deleted — a collage attacking his GOP primary rival Jeb Bush that featured a swastika. 

The tweet, which Trump manually reposted, was quickly circulated by various Twitter users and reporters, who took screenshots of the image and reposted them.

In addition to a swastika, the collage also used Hispanic stereotypes to promote an anti-immigration reform agenda. The campaign said Wednesday morning that Trump did not realize the image included offensive imagery.

“This was retweeted by Mr. Trump like hundreds of others. He did not see the accompanying image and the retweet has since been deleted,” Trump spokeswoman Hope Hicks said in an e-mail.

But the Republican front-runner, who is a prolific tweeter, has found himself embroiled in controversy several times during the last several months for posting offensive images to his social media accounts.

Last month Trump's account tweeted a comment disparaging Iowa voters who support his rival Ben Carson, insinuating they lacked intelligence. "@mygreenhippo #BenCarson is now leading in the #polls in #Iowa. Too much #Monsanto in the #corn creates issues in the brain? #Trump #GOP," said the tweet. In July, Trump’s account tweeted a graphic that inadvertently used images of Nazi soldiers.

In both instances, Trump said that an intern had committed the error.

The Bush campaign ribbed Trump on his previous social media faux pas, with Bush spokeswoman Kristy Campbell predicting that Trump would again blame the error on an intern.
