which tends to reinforce the idea that Trump not only does not understand how sarcasm works, but is also prickly enough to, use the excuse of sarcasm to play "I meant to do that!" when he has obviously goofed.
For an example of actual sarcasm by Trump, there is possibly this recent entry, where it sounds like Trump is saying "I love everybody".
See? That would be sarcasm. When someone says something we all know obviously isn't true.
Thus ends the lesson.
