NEW YORK (NewsNation Now) — The Trump Organization sued New York City on Monday for canceling its contract to run a golf course in the Bronx earlier this year, a move it said was politically motivated and should be reversed.

The lawsuit, filed in state court, says nothing in the 566-page contract gave New York City Mayor Bill de Blasio the right to terminate the deal after the president’s supporters stormed the U.S. Capitol earlier this year.

The company is demanding that it be allowed to continue to run the course, which has dramatic views of the Manhattan skyline, or that the city pay millions of dollars to buy them out.

The lawsuit is the opening shot in what is expected to be a protracted, and possibly costly, fight between the city and the Trump Organization, according to several lawyers who reviewed the contract and experts familiar with the business practices of the litigious former U.S. president.

“Mayor de Blasio’s actions are purely politically motivated, have no legal merit, and are yet another example of the mayor’s efforts to advance his own partisan agenda and interfere with free enterprise,” the Trump Organization said in a statement.

The city said Trump was clearly in breach of the contract terms and it will “vigorously defend” its decision.

When de Blasio announced he was kicking Trump off the course in January, he cited Trump’s “criminal action” in inciting Capitol rioters, arguing that he could fire him “for cause” and not pay him a dime.

The firing was part of a backlash against Trump after the Jan. 6 violence. Insurers, banks and brokers also refused to do any future business with the former president’s company.

Trump is facing a criminal investigation in New York, though he has not been charged with any crimes. Still, legal experts say this lawsuit could be put on the back burner if any of the investigations lead to indictments.

“I can tell you that pretty much any concern that you have falls away when you’re considering the possibility of an indictment and going to jail,” attorney Robert Bianchi said.

The city has also cited a decision by the PGA of America to cancel a tournament that was going to be held at one of Trump’s golf courses in New Jersey.

The city said that Trump could no longer argue he can attract prestigious tournaments to the Bronx course, called Trump Golf Links at Ferry Point, as is required in the contract.

In its lawsuit Wednesday, the Trump Organization said the contract doesn’t require it to attract tournaments, only obliging it maintain a course that is “first-class, tournament quality.”

It attached letters from course designers, golf organizations and famous golfers including top-ranked players Dustin Johnson and U.S. Open champion Bryson DeChambeau saying the course met that standard.

The city has previously argued that the Trump Organization was being “overly restrictive” in its interpretation of the phrase “first-class, tournament quality,” saying it need only show that Trump is incapable of attracting tournaments for whatever reason.

Under terms of the contract, New York City can terminate its deal with Trump at any time without cause, but would be obligated to compensate his company for money it invested in building a clubhouse on the course.

Trump’s son Eric, who lashed out at the city decision as a part of “cancel culture” earlier this year, has said the city would have to pay more than $30 million, a figure cited again in the lawsuit.
