Donald Trump Jr. took the stand this week in the New York attorney general's $250 million fraud case against the Trump family business, but said he couldn't recall key details about his and his father's involvement in the Trump Organization.

Trump Jr. — former President Donald Trump's eldest son — testified that he couldn't remember if Trump was still a trustee of the Donald J. Trump Revocable Trust.

He also said he didn't remember the time period in 2021 in which he was removed — and then reinstated — as a trustee.

When prosecutors from NY AG Tish James' office questioned Trump Jr. about whether he worked on Trump's statement of financial condition, Trump Jr. replied, "Not that I recall."

And he said he had no knowledge of why Trump added himself back as a trustee while he was still president.

James' office filed the massive fraud lawsuit against the Trump Organization, Trump, and his three eldest children last year, accusing the former president of falsely inflating the value of his assets on his financial statements.

(Donald Trump Jr. and Eric Trump remain targets of the case, but Ivanka Trump is no longer a defendant.)

Trump "falsely inflated his net worth by billions of dollars to further enrich himself and cheat the system" and "repeatedly and persistently manipulated the value of assets to induce banks to lend money to the Trump Organization," James said at a news conference announcing the lawsuit.

She said the Trump Organization's fraudulent activity allowed it to receive more favorable loan terms, pay lower taxes, and induce insurance companies to give lower premiums.

Trump Jr. was the first of Trump's children to testify this week. After his testimony wrapped up Thursday morning, Eric Trump took the stand. Trump and his daughter, Ivanka, are scheduled to testify next week.
