It’s a company owned by his family, bearing his family name that he ran personally for over half a century. How could a blind trust make him forget how to benefit it?

When his presidency is over, he knows exactly what company he will be going back to. It’s not like it’s a bucket of anonymous stocks, that he doesn’t care about except for it to gain in value. People with family businesses care more about the success of the business, than simply being rich.
