NORFOLK, Va. (AP) — President Donald Trump’s Justice Department is zeroing in on New York Attorney General Letitia James with a subpoena for records related to the $454 million civil judgement she won against Trump for lying about his wealth, a person familiar with the matter has told The Associated Press.

President Donald Trump’s Department of Justice on Friday issued a subpoena to Attorney General Letitia James’ office related to a new investigation over the civil fraud case she won against him, the same day prosecutors stepped up a separate mortgage fraud probe against her.

The move, disclosed by various media outlets, marks a significant escalation in the battle between Trump and the Democrat who prosecuted him for fraud.
