Donald Trump Jr. retweeted a tweet over the weekend that incorrectly identified a woman giving a Nazi salute outside a rally for Donald Trump as a supporter of Sen. Bernie Sanders (I-VT), according to Gawker.

Trump Jr. appears to have deleted his retweet of a post from Twitter account @voxday.

The New York Times identified the woman in the photo taken by the Chicago Tribune as Birgitt Peterson, a Trump supporter.

“The Republican Party needs to be broken up, and I believe Donald Trump is the one to do it,” Peterson told the New York Times.

She told the Times that when Trump’s Chicago rally was cancelled on Friday, she ended up near a group of protesters, one of which she said was holding a sign with Adolf Hitler on it.

“They said Trump is a second Hitler,” she said. “I said do you know what that sign stands for? Do you know who Hitler really was?”

“I make the point that they are demonstrating something they had no knowledge about,” Peterson continued. “If you want to do it right, you do it right. You don’t know what you are doing.”

She told the Times that she then gave a Nazi salute as a way to counter-protest.

“Absolutely I’m not a Nazi, no,” Peterson said. “I’m not one of those.”
