There is a painting in the White House, in the Red Room, titled “Castle Rock”. It was acquired in 1972. It looks like a simple landscape painting of a large rock out cropping on the seaside of Massachusetts.

Maybe Trump removed it along with other things; maybe that is a trigger, when the castle rock painting is removed?
Lol the Clintons even took the silverware if I recall.
