President Donald Trump lashed out at Nordstrom on Wednesday for dropping his daughter Ivanka’s fashion line.

“My daughter Ivanka has been treated so unfairly by Nordstrom,” Trump tweeted. “She is a great person – always pushing me to do the right thing! Terrible!”

White House press secretary Sean Spicer backed up Trump’s statement on Wednesday, saying Nordstrom’s decision was a “direct attack on his policies and [Ivanka’s] name.”

Nordstrom said last week that the brand’s declining sales led to its decision.

“Each year we cut about 10% [of brands carried] and refresh our assortment with about the same amount,” a Nordstrom representative told Business Insider. “In this case, based on the brand’s performance we’ve decided not to buy it for this season.”

The company reiterated that on Wednesday, saying, "Over the past year, and particularly in the last half of 2016, sales of the brand have steadily declined to the point where it didn't make good business sense for us to continue with the line for now."

The company said Ivanka was informed in early January about Nordstrom's decision.

Nordstrom dropped Ivanka's line amid calls for a boycottof retailers that carry Trump products.

In the days after the decision, other retailers including Neiman Marcus and Belk also stopped selling Ivanka's fashion line, which includes women's clothing, shoes, and accessories.

A representative from Ivanka's business said last week that sales are increasing despite the boycotts.

"The Ivanka Trump brand continues to expand across categories and distribution with increased customer support, leading us to experience significant year-over-year revenue growth in 2016," Rosemary Young, a senior director of marketing, told Business Insider in a statement on Friday.
