The accounting firm Mazars has fired the Trump Organization as a client after saying that a decade’s worth of statements of ex-President Donald Trump’s financial condition “should no longer be relied upon,” the New York Attorney General’s office revealed in a court filing Monday.

Mazars, which for years prepared Trump’s income tax returns and financial statements used to obtain loans for his company, told the Trump Organization’s top lawyer Alan Garten that it would no longer represent the company due to the lack of reliability of the financial statements in a letter last Wednesday.

(Trump has hundreds of millions in loans which come due early next year. It is now unlikely he will be able to refinance them.)
