Yep - unfortunately it does appear to be made up. And while it’s almost certainly made up amd perhaps goes way too far for at least realism, it’s not at all out of character for lots of shorter stories of Trump caring about, knowing about, and caring for those around. Those are easy to find.

So you say the agent us lying.
And Snopes isn’t? Their credibility died years ago. No different than CNN or MSNOW “fact checkers”.
