Surely you agree that having his family run it is an insane conflict of interest though, right?
No.
Maybe people should review what the term "conflict of interest" actually means. Receiving income from two or more different sources is not a conflict of interest (if it were attorneys would either be poor, due to having only one client, or would all be disbarred).
I can't easily imagine how the operation of hotels, restaurants or golf courses could give rise to a conflict of interest. The exception would be holding assets (hotels or golf courses) in foreign countries where we could have conflicts. E.g., Trump owning hotels and/or golf courses in Russia could be problematic. Imagine Trump (or Congress) imposes sanctions on Russia and Putin responds by confiscating the hotel or golf course in retribution.
Notwithstanding that last bit, I think the best course is no sales, no acquisitions. That would vastly minimize the opportunity for dirty money to flow.
I would like to say I'm surprised by the Dems sudden interest in conflicts of interest when the biggest I've seen has been staring y'all in the face for years now: A giant tax-free bank acct that anybody can come by and drop millions into with no oversight - it's called the Clinton Foundation.
