You can add Nordstrom next to the media, China, Saturday Night Live, Mexico, CNN, and Australia on the growing list of entities at war with United States President, Donald Trump. Last week, the upscale fashion boutique supposedly “dropped” the brand of First Daughter, Ivanka Trump, from their store racks, citing poor sales. Naturally, this raised the ire of the mogul-turned-politician.

Using his favorite form of communication, the President took to Twitter to lambast the company for its decision. Trump tweeted, “My daughter Ivanka has been treated so unfairly. She is a great person-always pushing me to do the right thing! Terrible!” This exact message was cross-posted on his Facebook and Instagram.

Nordstrom was thrusted into the public eye thanks to a growing movement called the, “Grab Your Wallet Campaign.” Critics of the First Family have urged shoppers to boycott retailers that have Trump labeled items on their shelves. This protest includes Ivanka.

Ivanka has drawn negative attention for her close affiliation with her father. Not only does she work for the Trump Organization, but she is also beginning to take a more active role in the White House. The same goes for her husband, Jared Kushner, who serves as an advisor to the President.

Donald Trump’s use of Twitter has raised a lot of his opposer’s eyebrows. “It’s never great to have these questions about dual allegiance,” said Jordan Libowitz,  who is a communications director for  a nonpartisan watchdog group called, “Citizens for Responsibility and Ethics.” He continued, “Certainly we’ve never seen before a president using the power of the presidency to pressure businesses for the obvious benefit of his family.”

It should be noted that Donald Trump’s tweets about Nordstrom came from his own personal account, and not that of @POTUS that he took over when replacing Barack Obama in the Oval Office. Feeling a blowback from the President’s tweet, shares of Nordstrom took a tumble shortly after. However, it has quickly covered. Nordstrom, who was a big proponent of Ivanka Trump’s band back in 2011, continues to stick by its decision of discontinuing the First Daughter’s brand. In a statement from the retail company, they reiterated, “Based on the brand’s performance, we’ve decided not to buy it for this season.”
