President Trump on Wednesday attempted to use his presidential clout to publicly attack a luxury department store for deciding to end its relationship with his daughter’s fashion company. Bloomberg reported the move by the Seattle-based Nordstrom last week as being performance-based. “Based on the brand’s performance, we’ve decided not to buy it for this season,” the company said in a statement. In a tweet on Wednesday morning, Trump fumed: “My daughter Ivanka has been treated so unfairly by @Nordstrom. She is a great person—always pushing me to do the right thing! Terrible!” The president’s rant against a private business over its dealings with his family comes in direct contradiction of his representatives repeatedly claiming that Trump is “completely isolating himself from his business interests” to concentrate on “the people’s business.” Hours later, during a White House press conference, Sean Spicer defended the president’s tweet: “He has every right as a father to stand up to them” for dropping Ivanka’s brand and that the company had engaged in a “direct attack” on Trump’s policies. A Nordstrom spokesperson later released a statement reiterating that the comapny’s decision was purely based on sales.
