Ms. James’s civil investigation is focused on the Trump Organisation’s business practices, though she can make a criminal referral and can seek authority from Gov. Andrew M. Cuomo’s administration or the state comptroller to bring charges on her own.
Her inquiry began last year in March, after Michael D. Cohen, the president’s former lawyer, told Congress that Mr. Trump had inflated his assets in financial statements to secure bank loans and understated them elsewhere to reduce his tax bill. In August, the attorney general’s office asked a judge to force the president’s son Eric Trump to testify in the inquiry, and he did so last month. Eric Trump is an executive vice president at the Trump Organisation, running its day-to-day operations.
