Two of the children of former President Donald Trump have refused to comply with a subpoena from the New York State Office of the Attorney General, and they are reportedly planning to sue to block the motions.

Ivanka Trump and Donald Trump Jr. denied the request from New York Attorney General Letitia James in the civil lawsuit which mirrors a criminal investigation of the Trump Organization by the Manhattan district attorney’s office.

The former president has also been issued a subpoena from the attorney general’s office.

“As her investigation into financial dealing of the Trump Organization continues, Attorney General James is seeking interviews under oath of Donald Trump, Donald Trump Jr., and Ivanka Trump,” read a statement from a spokesperson for the attorney general.

“Despite numerous attempts to delay our investigation by the Trump Organization, we are confident that our questions will be answered and the truth will be uncovered because no one is above the law,” the statement continued.

Trump has denied wrongdoing and criticized the investigation as “the greatest Witch Hunt in American history.”
