"While we have not concluded that the various financial statements, as a whole, contain material discrepancies, based on the totality of the circumstances, we believe our advice to no longer rely upon those financial statements is appropriate," Mazars said in its February 9th letter to Trump Organization attorney Alan Garten.

Monday’s disclosure of the letter comes as part of New York Attorney General Letitia James’ civil investigation into Donald Trump’s New York-based real estate business. The investigation partially overlaps with the Manhattan District Attorney’s criminal investigation, which James joined in May, into the Trump Organization’s practices. 

New York state’s attorney general claims the Trump Organization frequently misrepresented the value of its assets to obtain financial benefits.

Mazars said it had reached its decision based on a January filing by James, as well as its own investigation, and information for internal and external sources.

Mazars has said it no longer plans to work with the former president’s company. In response, a spokesperson for the company said it is “disappointed that Mazars has chosen to part ways."
