Since leaving the White House, Melania Trump’s world has become smaller. Just how she likes it.

Cloistered behind the gates of her three homes, she sticks to a small circle – her son, her elderly parents and a handful of old friends. She visits her hairdressers, consults with Hervé Pierre, her longtime stylist, and sometimes meets her husband for Friday night dinner at their clubs. But her most ardent pursuit is a personal campaign: helping her son, Barron, 17, with his college search.
