Of course he’s trolling. It’s obvious he’s trolling. And yes, he’s probably trolling in an effort to distract. And also: it’s a major problem that a sitting “president” is trolling, and it should be called out because he’s deeply, deeply unwell.
I think saying he’s “just trolling” is the same as saying he’s “just exaggerating”, which is what the media said about him all along and is part of what got us all here. Everything he says must be considered a genuine belief or desire on his part. To dismiss anything as trolling is too dangerous.
