One thing about Trump is he will go off script and say things that was said BTS when preparing for an official visit. The Zelensky situation  for instance. Someone must have mention that Ukraine does not hold the cards as metaphor and then he went on to blab about it in front of the world. SMH

I think going off script that's Trump's way of retaining some autonomy in the midst of people who help put him back in the Oval Office

It's true that Trump often goes off script to assert his independence and control in political settings. This approach allows him to maintain a sense of autonomy and unpredictability, which can be appealing to his supporters.
