I will admit to having only read the excerpt, but can you point out the hubris and arrogance in her statement? She thanked those that did the work, and thanked Melania for overseeing the preservation of a historical tree - by taking rootings from the tree to be planted.
Again, I am limiting my judgment to only this statement, as my distaste for Chelsea and her parents does not allow me to view any of them favorably, on the whole.
