Trump vs Nordstrom: The latest bout raising ethical concerns

Whereas other presidents took pains to avoid even the appearance of using their office for private gain, Trump is pushing the limits.

Trump's tweet follows revelations that First Lady Melania Trump expected to develop "multi-million dollar business relationships" tied to her presence in the White House, according to a suit she filed on Monday.

Ethics experts have criticized Trump's plan to separate himself from his sprawling real estate business by handing managerial control to his two adult sons.

Kathleen Clark, a government ethics expert, said the Nordstrom tweet is problematic because other retailers may think twice now about dropping the Ivanka Trump brand for fear of getting criticized publicly by the president.

Eisen joined with other legal scholars and lawyers to sue the president last month for allegedly violating a clause in the Constitution that prohibits government officials from accepting gifts or payments from foreign governments.

Though other legal scholars disagree, Eisen said such payments include foreign diplomats staying at Trump's new Washington D.C. hotel and holding events there and at the other Trump venues.

A Quinnipiac University poll found that about 60 percent of registered voters were at least somewhat concerned that the president would "veto a law that would be good for the country because it would hurt his business interests."

[...] a Pew Research Center poll found that 57 percent of American adults were at least somewhat concerned that Trump's businesses could "conflict with his ability to serve the country's best interests."
