NEW YORK (AP) — When Donald Trump became president in 2017, he handed day-to-day management of his real estate empire to his eldest sons, Donald Jr. and Eric.

Now, as the Trumps fight to keep the family business intact, the brothers are set to testify in the New York civil fraud case that threatens their Trump Organization’s future.

Donald Trump Jr. is expected to testify Wednesday and Eric Trump on Thursday, kicking off a blockbuster stretch as the trial in New York Attorney General Letitia James’ lawsuit enters its second month.
