The Trump Organization filed a lawsuit against New York City Monday, alleging that the termination of its Bronx golf course contract following the Jan. 6 U.S. Capitol riot was politically motivated.

Why it matters: The estimated cost of the decision by NYC Mayor Bill De Blasio to end all contracts between the city and former President Trump's family business in response to the insurrection is $17 million a year in revenue.

• The Trump Organization alleges in the wrongful termination suit that the cancelation would cost the company $30 million.

What they're saying: "Mayor de Blasio had a pre-existing, politically-based predisposition to terminate Trump-related contracts, and the city used the events of January 6, 2021 as a pretext to do so," states the lawsuit, which was filed in the New York State Supreme Court in Manhattan.

The other side: Per the New York Times: Bill Neidhardt, a spokesperson for the mayor, said in response: "Donald Trump directly incited a deadly insurrection at the U.S. Capitol. You do that, and you lose the privilege of doing business with the City of New York."
