NEW YORK (AP) — Donald Trump Jr. testified Wednesday that he never worked on his father’s financial statements, the documents now at the heart of the civil fraud trial that threatens former President Donald Trump’s real estate empire.

The ex-president’s eldest son is an executive vice president of the family’s Trump Organization and has been a trustee of a trust set up to hold its assets when his father was in the White House.

At least one of the annual financial statements bore language saying the trustees “are responsible” for the document. But Donald Trump Jr. said he didn’t recall ever working on any of the financial statements and had “no specific knowledge” of them.

The lawsuit centers on whether the former president and his business misled banks and insurers by inflating his net worth on the financial statements. He and other defendants, including sons Donald Jr. and Eric, deny wrongdoing.

Trump Jr. said he signed off on statements as a trustee, but had left the work to outside accountants and the company’s then-finance chief, Allen Weisselberg.
