If that is how Tiffany feels (Redheaded Stepchild), it may be because everyone knows how her mother came to become the second Mrs. Trump. Horse stealing, some would call it.
Mr. Trump, by all appearances, seems to genuinely love all his children. Even still, I have not seen any photos with Tiffany’s mother from inside the White House. I’m sure she must have visited by now.
One of the exes, I think Tiffany’s mom, supposedly left the inauguration festivities early so as to not bump into the other ex.
