WASHINGTON Cork Wine Bar is suing President Donald Trump and his Trump International Hotel in Washington, D.C. , for unfair competition. The lawsuit claims that the presidents ownership and promotion of the hotel gives it an unfair advantage in attracting business for its restaurants and its bar, which are likewise owned by the president.

The lawsuit was filed in D.C. court as a common law claim, asking the court to issue an injunction declaring that the hotel is competing unfairly with local businesses. If an injunction is ordered, the plaintiffs are looking for the court to demand that the Trump Organization resolve the issue. That could involve divesting from the property and the lease.

The owners of Cork, Diane Gross and Khalid Pitts, who are married, are not seeking monetary damages. The legal team involved in the case includes Mark Zaid, Scott Rome, Steven Schooner and Alan Morrison.

Trumps hotel in D.C. has been at the center of concerns over his refusal to divest from his multibillion-dollar business. On Jan. 11, Trump announced that he would simply hand control of his many businesses to his adult sons Donald Jr. and Eric. But the president still maintains ownership of every one of his businesses and benefits financially from every dollar spent at his hotels, golf courses and commercial and residential buildings.

Since Trumps election and inauguration, the Trump International Hotel has seen a massive boom in business. Foreign governments have moved their annual parties from other venues to the Trump hotel. Management hosted an event to sell foreign diplomats on staying at the hotel to curry favor with the White House. Wealthy Trump administration appointees like Treasury Secretary Steve Mnuchin, Small Business Administration head Linda McMahon and National Economic Council director Gary Cohn all live in the hotel . Sean Spicer, one day before assuming the job of White House press secretary, encouraged people to go there if you havent been by . Trump has even patronized the hotels restaurant to eat his customary well-done steak with ketchup .

The lawsuit addresses unfair competition that derives from what is the most dramatic conflict of interest ever involving a President of the United States, said Schooner, a government procurement expert at George Washington University Law School.
