“You would have a bunch of people who know nothing about taxes trying to look through and trying to come up with assumptions on things they know nothing about,” Eric Trump said Wednesday on CNBC.

“It would be foolish to do. I’m actually the biggest proponent of not doing it.”

Donald Trump, the Republican presidential nominee, has faced criticism for refusing to release his tax returns.

He has repeatedly pushed back against calls to release the documents, saying he is under audit by the Internal Revenue Service (IRS).

The IRS has said nothing prevents Trump from releasing his tax returns.

Eric Trump said on Wednesday that there is "no tax attorney in the world who will tell you to release your tax returns while you're under a standard routine audit."

He added, "You don't learn that much from a tax return.

"You learn a lot more when you look at somebody's assets. You know how many hotels we have around the world. You know how many golf courses we have around the world. You know every single building we have."
