Former President Donald Trump filed a lawsuit Monday in an effort to block New York state Attorney General Letitia James from continuing to investigate his business.

James is conducting a civil probe of the Trump Organization, focusing on where the company has misstated the value of real estate assets to obtain favorable loan and insurance rates, while lowering its tax obligations.

That investigation is mirrored by a criminal investigation being conducted by the office of Manhattan District Attorney Cyrus Vance Jr.
