Trumps kids can do WHATEVER they want to build a business if Don Jr. were to go into the media there is not one damn thing ANYONE can do about it let them SCREAM all they want to!!!
Evidently you’re not aware of the Emoluments Clause issue that Trump’s enemies are already badgering him with.
Having a family media empire created while he’s in office would just give the Left another opportunity to cause trouble for him.
