That is the delusion Trump operates under. If one looks to British royals they serve as international liaisons for the sovereign. Trump takes example from that lineage to pretend to be the equivalent to the Royals.
Trump is very delusional with many things. Believing he is more than a president, but, the dictatorial equivalent to a sovereign.
The Brits (click here) had it figured out. Trump’s first trip to the UK was a complete disaster. He disrespected protocol and made a laughing stock of the USA. So, Charles and Camilla went to great lengths the next time to hem Trump in by treating him, not as a president, but, as a king. And it worked. Trump and Melanie behaved themselves.
If the people of the USA are expecting a “normal” presidency from Trump they are in for a surprise. He has many personality disorders and the nepotism is all part of it.
It is just a shame Trump has to be interrupted to rubber stamp outrageous demands of his donors through his cabinet staff. He much rather eat his hamburger and watch FOX News than have to keep everyone happy with him. Everyone is supposed to be making him happy.
