Trump's comments underscore the complicated relationship that the wealthy New York real estate developer who became president on Jan. 20 has with his sprawling family business interests amid criticism from Democrats and others about the ethics and legality of the arrangement.During a White House briefing, Spicer painted Nordstrom's action as an attack on the president's daughter."For someone to take out their concern with his policies on a family member of his is just not acceptable. And the president has every right as a father to stand up to them," Spicer said.Nordstrom did not respond to requests seeking comment. A spokeswoman for the Ivanka Trump brand declined to comment.The Republican president's complaint, however, drew swift criticism from Democrats. Asked about the Nordstrom tweet, U.S. House of Representatives' minority leader Nancy Pelosi said:"I think it's inappropriate, but he's a totally inappropriate president, so it's totally in keeping with who he is. What I think is more inappropriate, though, is for him to refer to a judge who made a ruling that he didn't agree with as a 'so-called judge.' Now we're talking about the separation of power, not the thin skin of an incompetent president," Pelosi told reporters in Baltimore for House Democrats' retreat.Senator Bob Casey, a Democrat, in a tweet indicated that the matter should be referred to the Office of Government Ethics:My daughter Ivanka has been treated so unfairly by @Nordstrom. She is a great person -- always pushing me to do the right thing! Terrible!

Trump's web of international companies remains a bit opaque since he has refused to release his tax returns, which experts have said would provide a clearer view of his business interests.Since winning the U.S. presidential election on Nov. 8, Trump has targeted specific companies on Twitter. But this is his first tweet criticizing a business tied to his family since the victory.Ivanka Trump ran a clothing and jewelry business bearing her name, in addition to other work for the Trump Organization, before saying she would resign when her father was sworn in as president last month.ProPublica reported on Feb. 2 that the Trump Organization said Ivanka had resigned her positions but that it had not yet filed the changes. The Trump organization later said the filings would be done by Feb. 3, according to the report.Shares of Nordstrom fell 0.7 percent after the president's criticism but recovered to trade up 3.7 percent at $44.38 on the New York Stock Exchange.
