President Trump on Wednesday took to Twitter to blast Nordstrom for its decision to stop selling his daughter Ivanka’s luxury fashion line.

“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 leader of the free world tweeted — on both his personal and official POTUS accounts — about 10:45 a.m.

The high-end retailer said last week that the brand’s declining sales led to its call to drop Ivanka’s products.

“Each year we cut about 10 percent [of brands carried] and refresh our assortment with about the same amount,” a Nordstrom rep told Business Insider.

“In this case, based on the brand’s performance we’ve decided not to buy it for this season.”

The retailer dropped Ivanka’s fashions following calls for a boycott against retailers that sell Trump products.

The parent company that operates TJMaxx and Marshalls discount apparel chains are also downplaying Ivanka’s line, a new report said Wednesday.

TJX Companies told employees not to display Ivanka merchandise separately from other brands and to throw away Ivanka Trump signs, according to a note to employees obtained by The New York Times.

“Effective immediately, please remove all Ivanka Trump merchandise from features and mix into the runs,” the note read.

“Runs” refers to the usual racks where most products are displayed on hangers. “All Ivanka Trump signs should be discarded.”

A spokeswoman for TJX, Doreen Thompson, confirmed the message.

“The communication was intended to instruct stores to mix this line of merchandise into our racks, not to remove it from the sales floor,” Thompson told the paper.

“We offer a rapidly changing selection of merchandise for our customers, and brands are featured based on a number of factors.”

Response to Trump’s use of his official Twitter account to complain about treatment of his daughter’s business was quick and in some cases harsh.

“You’re mentally ill. Please see a medical professional,” tweeted City Councilman Corey Johnson (D-Manhattan).

Howard Wolfson, a former aide to former Mayor Mike Bloomberg, also weighed in.

“I just bought a gift card in response to president’s attack,” he tweeted, referring to Nordstrom.

Sen. Bob Casey (D-PA) also ripped the tweet — writing “CC”ing the Office of Government Ethics.

Casey “feels it is unethical and inappropriate for the President to lash out at a private company for refusing to enrich his family,” Casey’s press secretary Jacklin Rhoads told Politico.

“It’s never great to have these questions about dual allegiance,” said Jordan Libowitz, spokesman for Citizens for Responsibility and Ethics in Washington, a nonpartisan watchdog group, told Bloomberg.

“But 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 was only the president’s latest squabble with corporate America.

In the past he’s picked fights with Carrier, United Technologies, Boeing, Lockheed-Martin and Ford over a host of issues.

Trump also had an earlier feud with Macy’s Inc., which previously sold his brand of menswear.

The department-store chain split with him in 2015 after he criticized Mexican immigrants at the outset of his presidential campaign.

Trump called Macy’s a “very disloyal company” and urged a boycott.

Nordstrom had circulated an internal memo in support of immigrants after Trump unveiled his travel ban.

The boycott was organized by a group called Grab Your Wallet, a mocking reference to Trump’s infamous line that he could grab women “by the p—y.”
