NEW YORK (AP) — New York’s attorney general recently subpoenaed former President Donald Trump’s two eldest children, Ivanka and Donald Trump Jr., demanding their testimony in connection with a civil investigation into the family’s business practices, according to a court filing made public Monday.

The subpoenas, stemming from Attorney General Letitia James’ yearslong investigation into matters including “the valuation of properties owned or controlled” by Trump and his company, the Trump Organization, came to light after James went to court last month seeking to force the Trumps to comply.

A state court judge who handled past disputes arising from the probe agreed Monday to entertain arguments over the subpoenas, which also seek documents from the Trumps in addition to their testimony.
