I was watching live when Trump called in, and the astronauts were clearly trying to emphasize the benefits of diversity and co-operation, and I'm quite sure none of that sunk in. Trump was too busy mispronouncing names, not knowing the difference between the name of the mission and the name of the craft, big noting his own role in funding NASA (while his administration has been actively attacking NASA) and generally waffling on because he likes to listen to himself speak.

The next call after that also had the NASA director comment something like "I'm sure this call won't be as special as that last one" whereupon commander Wiseman burst out laughing so I'm pretty confident those involved in the mission are not in Trump's camp. Which is to be expected, because their jobs require them to be humans with functioning brains.

The Russian scientists on the ISS are all Putin fans, though.
