NEW YORK (CBSNewYork) — The Trump Organization’s Chief Financial Officer Allen Weisselberg is expected to face charges Thursday in New York.

The charges stem from a years-long investigation led by Manhattan District Attorney Cy Vance Jr. into the organization and its CFO.

Sources tell CBS2 that Weisselberg was indicted Wednesday night by a Manhattan grand jury. The exact charges will be unsealed Thursday, but sources say they are likely tax charges related to payments on apartments, cars and even private school tuition.

Weisselberg’s estranged former daughter-in-law is a key witness, who turned over several boxes of documents.

While former President Donald Trump has been the face of the company, Weisselberg has operated behind the scenes as CFO and the family’s personal bookkeeper.

In a statement earlier this week, the former president railed against prosecutors for going after “people within the Trump Organization.”

In 2019, Michael Cohen, the president’s then-personal attorney, testified that Weisselberg never acted alone.

“Everything was done with the knowledge and at the direction of Mr. Trump,” Cohen said.

Trump, however, is not expected to face charges, but he’s not in the clear. A grand jury is still sitting until November, so it’s possible he could see indictments.

Trump Organization lawyers told CBS News they will try to dismiss any charges, and they believe the threat to the organization is disproportionate to the alleged misconduct.

“Mr. Weisselberg intends to plead not guilty and he will fight these charges in court,” his attorneys said in a statement after his surrender Thursday.
